I have the Corsa with stainless works and catless on 10 lbs of boost. It's godly loud. But corsa did well with the muffler design and placement. So still no drone.

Installed over the weekend. Still a few loose ends to tie up before a full blown test. Pun intended.

I'm not worried about warranty. Id rather build it my way. If i blow an engine, just a great excuse to pull it and build it back bulletproof. And still cheaper than callaway/hennessey. To each their own tho.

 

HP tuners ecm is on the way. Ill probably get the Whipple on in the next few weeks. 

You sent HP Tuners a new ECM and kept your original, right?  What did you do to the ECM prior to shipping it to them?  Their instructions refer to performing the Replace ECM Function in VCM Scanner for the stock ECM.  Was this something you needed to do to the new ECM you sent them?

nt them?

I sent HP the new ecm. You have to give them your VIN. They unlock it and send back. Nothing needs to be done on the ecm before sending. Its an exchange, you dont get the exact one you send them back anyways. To finish the process, once you get the ecm back, you use the vcm scanner, download the info off the stock ecm, peform the physical swap, and re-upload.

Thank you, that is what I thought but just wanted to ask anyway.

Does anyone have any custom tuning they would be willing to share? Whipple and ProCharger supply a canned tune, but they are limited/minimal to stay within emissions regs. Obviously a tune is specific to vehicle, just figured it may be worth an ask and more discussion. May even need a new post instead of under this one.

Having a shared file for your truck would not be a good idea. You really need to get a tune done at a shop to make sure your good to go.

This might be a dumb question... Should I have the Chevy dealer use my tablet to do the tuning with the HP Tuners software loaded on it to make sure I retain ownership of the credits and the tune? Or, does that really matter?

Looking good!  Give us a full report once you get her on the road. 

The 6.2 is pretty awesome naturally aspirated. I had high expectations, and Whipple didnt let me down. The power is pretty crazy, especially in a 4 door pickup. No check engine lights, leaks, or issues whatsoever.

 

Id say what impresses me just as much as a full throttle pull, is the torque at lower rpms. On the first run, i idled around the neighborhood and barely had to touch the throttle.

 

Haven't got used to the trans yet. Seemed like it wasnt sure which gear it wanted. Punching it from a 20mph or so roll and she seemed to hesitate on which gear to grab. I havent heard much about tuning the trans yet, but i can see the value of dialing it in. As is will take some getting used to.

Its pretty crazy how many wire harnesses, coolant lines, etc are crammed into the engine bay. I organized mine best i could, but theres just a lot in there.

 

Going to add a couple more lines with a catch can too.

 

Anyone mess with the trans tuning yet?

      NEW TRUCK

      By PUSSLEGUT · Posted

      I have finally paid off my mortgage and can now purchase a new truck. I would greatly appreciate any opinions on the purchase of a new 2026 GMC Denali 5.3L or 6.2L with the Denali reserve package. I am not interested in the 3.0L.  Or should I go buy a Ford?   Thank, John

      One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...

      L8S For 2027

      By C/K Man · Posted

      'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine.

      New Duramax rumor?

      New engines will still be using DEF. You just won't have the limp modes occurring when you run out of DEF now.

      first oil change - 2026 2500HD gas

      By bruceb58 · Posted

      I am not a NOCO fan for a charger I would leave on a battery 24/7. The reason is, it doesn't really float. It waits until the battery drops to a certain voltage and then charges it back up to 14V. It's better than no charger I guess.
