I am also interested in the actual power gains from the chip. A claimed 37HP and I believe 32ft-lbs of torque for around 300-400 sounds like a bargain to me, but am I going to feel it, and is it worth it? Being that right now I can probably only afford a '91 with over 100,000, I am not going to have the funds to cover a rebuild, nor would I want to. Thanks again Ryan
