 Ok fellas I know you all are the pros, I just bought a new 2017 highcountry with the 6.2/ 8 speed. Apparently no one can tune the tcm, so I decided to buy a diablo i3 since I’m familiar with it, was gonna go BLACKBEAR but they refuse to answer emails or phones, so here’s what I’m asking!!

 

what bolt I s Can I buy to get the most out of this truck, I’ve read I should not swap my manifold to the vet manifold or the msc due to losing mid range and that since I have the 8speed it won’t matter much. However let me know your opinion?

 

* what cold air intake

* what throttle body upgrade

* should I upgrade manifold

* what are the best header option 

* I already added the cat back borla exhaust

* am I missing anything, I’m gonna start buying ASAP so LLEASE HELP

Just do an afe momentum gt intake and ARH headers and call it a day.

 

The exhaust system and the intake before the manifold are the big restrictions.

 

should be right around 500hp crank with that stuff and a tune. If you wish to retrofit for e85, that’ll get you about another 40hp crank

USMC considering the warranty issues with your 14 I would probably hold off on doing anything unless your dealer does the same assurances in writing.  With that said AFE cold air intake will help it breathe better with your Borla system.  

Happy Veterans Day and thank you for your service.??????

I have a 14 6.2 and did the afe momentum gt Intake, Texas speed stainless headers, and dyno tune. Right at 390/420 on 33s is what it put down. Made a huge difference. Kinda wish I had done it on stock tires to see what it could really do. I wouldn’t mess with the throttle body or the manifold unless you planned on going further than bolt ons

The CAI, Borla exhaust and tune are no brainers. Going bigger on TB/intake not so much as this is a truck it is lower RPM Torque. The TB/Intake would be for higher end HP but you will most likely lose some lower end torque.

50rwhp for ricer bolt ons is hilarious for a naturally aspirated motor. My headers on the way, intake is installed, Procharger p1sc next? Anyone running the basic procharger kit with bolt ons?

Add the headers a 2.9 Whipple and an Alky control kit with your 102 TB and you will be over 600 at the tire

Let me know if you end up getting these.  That price seems to GOOD to be true.
I was looking into them and they are actually a local company. I might go down and check them out in person if they let me.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
