Thanks, it was a great trip and well worth it. The ballpark cost is $200 to 250. They don't dyno trucks because of the danger of the drive shaft coming apart and messing up the truck and/or his dyno. He does have a super nice dyno. They only street tune trucks and they do a lot of late model GM trucks. They have street tuned an '06 Hummer H3 and an '11 Silverado 5.3 with a 3.08, for me, during the last five years. Everyone of them have been unbelievable results, especially the Hummer.

I have received numerous PMs asking about my tune, so many in different threads, I don't believe I could find them all, so I thought I would just initiate a seperate thread to address it. This may be

I just had Black Bear tune done and wow my truck at full throttle shifts into 4th at 100 mph. Transmission shifts so much better. Throttle response is fantastic. Best tune I have ever had done.

Ok, there seems to be a little confusion and a lot of misinformation passed around the internet that WILL eventually bite one of us in the butt when they go in for a warranty after they get their truc

CAI will be coming out with theirs in the near future.

The CAI I'm running is the Airaid designed for the 5.3. One of the other guys on here, TJay, did it first and then I followed his lead. The system works unbelieveably well, looks great, fits like a glove. Airaid says they don't plan to build a specific model for the 6.2 since this one serves the same purpose. It also has a huge snorkel coming out of the bottom of the air box that hangs down behind the grill, and man does it suck some air. It is definitely the best CAI system I have ever owned, and I have had 15 or 20 or them in the last 30 years. You are right, you can't find anything specifically marketed for the 6.2 yet.

 

As for the exhaust system. Mine is a custom cat back installed by a performance exhaust shop here in town. (Montgomery, Alabama). We simply cut the factory system off just behind the third cat and through it away. Then installed a 22" Magnaflow, single in, dual out, and fabricated two pipes to come straight out the back. The last 22" of the pipes are 4" chrome. Hope this helps. For what it's worth, I wouldn't change a thing on either system. They both far exceeded my expectations. Good luck with yours.

I have a roto fab cai on my camaro and a K and N on my truck now. I love the roto fab, the k and n is kind of meh.. so to say. I dont know much about airraid so will need to do some research I guess. I do know I didnt really care for their closed box design on the camaro vs the open filter style of the roto fab...

 

As for the exhaust.. I also have a local pro shop... Im going to PM you for some more info on that :D

Thanks for the update CorvetteOJ.

 

I had a PCM For Less tune on my 2003 2500HD. Night and day difference!

 

Looking forward to future updates!

CorvetteOJ can you post a clip of your exhaust I have been trying to decide between the 22 and 18 inch magnaflow muffler. Also was wondering if that shop will reset to oem specs if you need to take it to the dealer? I live about 2 hours from Mooresville so it wouldn't be a bad drive to have a tune done there.

I'm sorry, can't post a clip due to my being technically challenged. Yes, they will reset it any time you want. As for the difference between the 18 & 22" magnaflow, I can't say, I have the 22" but have wondered if I made the right decision. Mine is pretty nice but my exhaust guy tells me the18 would give me more rumble. Good luck with your decision.

Alvin knows his stuff, he tuned my Trailblazer SS for me via the mail order tune back in the day. I may have to inquire about it again in the future as I have HP tuners myself. I would only be out the $100 for the license and his fee as well.

The "Dealer" CANNOT see the changes BUT... On the 2014's which are now on the global platform like the Vette and Duramax have been on since 2010, they can now tell if the ECM has been flashed by way of a little hidden flash counter built into the system. This means... Say the dealer has done a couple flashes so far like on the Recall and maybe another TSB, this would have the counter set to a 3 (factory flash+recall flash + TSB flash). You come in because you have a transmission failure or dead miss in cylinder 4, dealer will more than likely be instructed to pull an image and history on ECU and send it in so that engineering can see what may have caused it, BAM! There sits a flash counter showing a count of 6 when they know that it should be set at 3.

That's when they give you that ever so polite quote of $7400 to repair vehicle while you are trying to argue that it is still under warranty.

 

We have been getting away with it for a long time, unfortunately the Dealer has the upper hand until some 9yo inner city Hacker Prodigy decides he wants to sit down for 45min one night and trick the system that hundreds of college grads have been working on for a few years.

 

Now if-when-and how often the dealer actually snaps an ECU image and history for diagnostics is a different story. My Dealer that I just stumbled across today told me they will do all they can to keep that from happening as long as I am upfront about tuning on it. The dealer I had yesterday all but threatened to drop my warranty for putting Drop/leveling shackles on the back of my truck

On our 14 Sierra, the biggest gains were inthe throttle response. I felt the factory throttle cal was about the worst offered by GM ever, and after some fine tuning, we were able to make the throttle much more lively, and we offer the end user further adjustment to make the throttle response work to your liking :)

 

Theres also a solid 20 rwhp/20-25 ft-lbs in the tunes...

 

Our tunes can't be seen by the dealer either ;)

Mike...

 

I love your matter-of-factness (pretty sure that's not a word) I tune with one of the two major software platforms available for GM products, have been doing it for right at 10 years and am pretty sure that the dealer could tell using my software. I know you guys put a lot of time and research Into your product and don't doubt your claim but.... let's just say that I purchase from you and install, would you be willing to carry warranty for the rest of the term? (Only If GM dropped me for finding the modification to ECU of course?)

 

I will start researching what you have to offer while I wait for your response.

A lot of people run Diablo with a custom. I like working with Black Bear myself. Their staff is very helpful

I got a 5.3 tune from Black Bear.

Noticeable increased throttle response and pulls much harder above 2500 RPM.

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.

      About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.

      Bridgestone vs Goodyear tires?

      By Vu1can · Posted

      Maybe I was just too unlucky, but I had nothing but bad luck with Bridgestones. Out of 3 sets, they all started losing a lot of air when they got down to about 1/2 tread life, and at that point also wet traction suffered more than it should have. Also, the only tire I ever had in my 60 years of driving that had a side wall blow out was a Bridgestone.   I'm currently running Goodyear Wrangler Workhorse AT and am very happy with them.

      maybe when the trip is over, check all the other joints in the front end, like all the ball joints, tie rods, pitman & idler arms, etc...
