Attention TDI drivers: Get a RocketChip!

It’s really a reprogramming of your car’s fuel management EPROMs. But look at what it did for my car:

+25 HP (U.S.)

+45 lb/ft. (+61 Nm)

which for my VW Jetta TDI means roughly

125 @ 4000 RPM

222 lbs/ft (~300 Nm) at 1800 RPM


It’s become a brand-new car, far more powerful than the old one. I think it handles better and shifts better, too, although the reprogramming didn’t do anything to the handling, nor certainly did it do anything to the transmission. But my god does it like to be shifted!

Best part is, it still handles gentle as a babe if that’s how I drive it. Or if I floor it while in first gear, I’m gone like a flash! It’s now easy to reach 80 MPH in fifth gear — imagine that! Fifth gear in a diesel car is fantastic for low fuel use, but not for acceleration. Not until now anyway!
