I've noticed when my truck is cold, and I go to stomp on it it runs great. After a while and warm or hot it's a slug. Going down the road at 65-70 mph and stomp it it is on top of its game. Why the sorry performance any other time. I changed my Banks chip for a TS 6 pos chip and I figured it would change it but it runs best on the 100hp setting. Where should I start looking? And fuel mileage sucks! Could be a problem with right foot though! Thanks guys!
