Hypertech 345752 Power Programmer III Automotive Tuning Computer

Plain and simple, I bought this for my 1994 Corvette. In doing research, I found that other Corvette owners either like it or hate it.I suppose it depends on what you want it to do for you. Will it turn your LT1 into a firebreathing drag racer? No. What I wanted is for the fans to come on much sooner to avoid hitting the 225 degree temps, and I wanted to firm up the shifts. I also added the custom engine tune. Did it do what I wanted? Yep, and I am happy with that!

Amazon price and service are great...but **BEWARE** of HyperTech.I purchased one of these and they refused to update the program chip when it became obsoleted by newer on-board computers.They wanted to charge me $250 for an updated chip. I'd try a company that takes better care of their customers.
