Need help

Post by GMC1500HD »

I just tried to install the 87 octane tune to my 05 gmc 1500hd 6.0l and it turned into a dog. Seemed super rich and felt like i lost 100hp. Did I do something wrong or do I just have an outdated version. I reset the factory tune and it's back to normal. I'm real new to this so any help is appreciated.

Diablo performane tune worked much better. 1st gear is still a dog but midrange and top end noticable difference.

What's with your website? I can't get on through google. Its been deemed unsafe? I can only get on through my phone. Anyway, do you have any suggestions?
