I have a hypertech 160* T-Stat and i put it in when i did my PI intake swap after my stock NPI intake craked. The reason i ask is my car just dont feel like it has any power at all anywhere and i cant figure it out, it is driving me insane. Every now and then it will run fine but most of the time it is not. What do you guys think it is?? I have replaced Plugs, Wires, Fuel Filter, Tranny Filter and Fluid, Cleaned K&N. It still dont run right. It does not surge, jerk, or anything like that. I need help!!!!!
