ASAP Emissions Intact tuning

[AZsurveyor]

My 24 shifts terrible. If I do nothing else I would love to loose those terrible shift flares. Honestly the 10 speed trans doesn't seem to know what it wants. The other day I was towing some rock and it started out on an incline sluggish then I noticed the trans was already in 4th gear and engine RPM at 1000. I'm now considering ASAP TCM only. What company should I consider to purchase the tuner and TCM tune?

If you are experiencing shifting flares, I recommend trying a relearn strategy.

I had this issue last year after tuning, but it can also happen from sudden acceleration or jerking of the transmission, such as suddenly romping on it.

Aggressive driving can also cause the transmission to need “relearning.”

It’s simple, find a long, flat stretch of road with no traffic, and follow the instructions to perform all the upshifts.

This fixed my problem and my shifts have been flawless ever since.

Im not paying $1,800 and giving up my warranty for a piddly40 hp. And I seriously doubt there's 40 safe HP to gain.

Why do you say that? Sincerely curious.

Why do you say that? Sincerely curious.

Because Gayle said so, and nobody else knows anything.

I'm calling bullshit

Here are the actual stock at the wheel numbers for all 3 '25 diesels.

You gonna trust the word a guy that calls himself "Duramax" to be honest about power figures?

Where are his fucking charts? Show me the curve.




At this point, I'm just having fun.. I hope you guys find whatever it is you're after, and may all your tuned trucks be trouble free.

But for REAL. show me some 0-60 videos.

None of y'all have proven a Damn thing, until you post some videos of sub 4 second 0-60 runs.

In other words. ... all y'all be full of it .

Here you go. Here’s an emissions on chart from AMDP. The emissions on tunes absolutely deliver higher HP contrary to what you keep spouting. You can find charts for ASAP or PPEI (who only does emissions on) or anyone else online. It’s not that hard yet you make these claims without doing any research yourself. It’s honestly pathetic and annoying.
