At the risk of asking a question that I'm sure has been asked many times before. I have a 92 LT1 coupe with auto that is completely stock and like many of us, would like to increase HP and TQ via the CHIP. Is there a best chip for the non programmable 92 computer? I've seen and read ads for Hypertech and JET and I'm sure there are more out there but not a clue as to which one to choose. Some need a Thermostat (160 deg) to work properly or to get the most performance from the programming. I've seen prices differ by $100 or more and I'm willing to spend the extra cash for piece of mind knowing I wont destroy the engine. Any response from those with after market chips would be appreciated.
