Yessir. I will try to get a couple screenshots when I get home. If you want, I can PM you my email address, and you can send me a copy of your tune. Then we can confirm I am seeing same info as you are. I actually have unlimited credits for 2002 Chevy/GMC trucks. When I got my HPTUNERS 15 or...

I just installed new heads, cam, LT headers, TBSS intake on my ?02 Silverado LS. Has factory 3.73 gears. I bought an HP tuner with 2 credits, now have to pay for a training class to unlock ?read only? columns to get deep into tuning. Once I get the AEM wide and installed I will take the class and...
