Hey, alright heres my problem. I have a 2.0 Zetec with a JR supercharger. lately my car has been running very crappy and I have pretty much zero throttle response. When I race If I don't smoke my tires almost up to 6000 then the car is slow through 1rst. Also in second the car is slow in acceleration up to 3,500 then it rockets from there on up as if it received a shot of nitrous. After racing for awhile the car runs worse, but If its cooler outside then it begins to run awsome. I understand that the heat might be causeing early detonation. Does anyone have a opinion on as to what I should do. I have been thinking about putting a intercooler and CO2 soleniod on it to get super cool air into my engine, but don't want to spend the money if It wont help. PLEASE HELP!!!!!!
