Does anyone make a performance computer chip for my '92 egt or my '92 protege lx? I tried a performance module from ebay for $48, but it was a sham! It didn't do anything at all! I enduro race my car, and i can't modify anything externally, so I want to get a chip. It has to be inexpencive, and must not be a sham (fake)! If there is one, how much power will it add, and how much will it cost? I would want it to add at least 5hp, the more the better! Gas mileage is NOT a concern, and I don't need low end torque, just high rpm hp!
