Did you 0 out your variable camshaft tables?

SILV,
The new exhaust didn't cause it, it was doing that before. It is just getting worse now that it's warmer outside. The tuner had left mine in MAF only so I am already there too. My guess on...

Hey guys,
I have a 2015 Silverado that has a Maggie TVS 1900, Gwatney Performance low lift (.540 lift 215/230 duration) cam and DOD delete kit, Texas Speed long tubes, and a Speed Engineering 3"...

Here are 2 videos I found very helpful to get started:

Use these as a guide, I was much more...

Make sure the shop that put the trans in won't void their warranty. That may be why they flashed a stock tune back in.

I have a 2015. While passing someone on the way to work one day it dropped #7 and I had to abort while passing and get back behind them. When the dealer called me they said I had 0 compression in...

Update on this. Changes flashed in this morning: all Torque Request Limit tables maxed out as explained in the other thread mentioned above, and took Mbrowning's suggestion but did a 10% increase on...

I would say yes.

Yes it does seem overwhelming at first. I just got HPT around Christmas. You can pick it up fast, just work on one thing at a time. I also worked on the trans in my 2015 Silverado first and it will...

Thanks, I will try that. I did also find out GM has an updated pedal assembly too. Verified my truck has the old part # so I will try that too when it arrives this week.

Hi guys,
Pretty new guy here. Happy with my progress on trans tuning so far on my 2015 Silverado, now trying to get rid of as much throttle lag as I can. From my searching it appears that is in...

Thanks for the reply. I am still tweaking, just want to make sure where the "line" is as far as line pressure, shift pressures, etc. I like where it is right now as far as the shifts.

Hey guys,
Pretty new to HP Tuners, have been playing with the tune on my daily 2015 Silverado, 5.3/6L80. Biggest thing I wanted to work on was the trans as that is my biggest complaint with this...

Staytuned - What exactly have you changed in these tables? I have been playing with my 2015 Silverado, have the trans shifting how/when I want, working on fuel maps now (very little needed), but...
