I have developed something that is providing very impressive mileage gains on every TBI GM Product I have tried it on, with increases in horse power and torque as well.
It's called "The Gadgetman Groove".
I've got a number of testimonials, including one from Kyle Geng of Phoenix, AZ telling about his gains. I'm trying to imbed that here. If that fails, I'll put in the link.
