I'm getting ready to order a new prom for my 84'. I've got some literature from Performance Resource saying their chips are the best. They compare theirs to ADS, GM, Guldstrand Engineering, Hypertech, and TPIS. Is there really any difference between the different chips, and also, since many have 1 & 2 stage chips, which chip offers the best balance between performance and general driving? What I'd like is a chip that offers good driveability/economy at low throttle speeds, and stonger performance at say 60-100% throttle. I have flowmasters, a new cat, and a 160 themostat and switch installed. :confused :confused :confused
