disconnect SLN- (Red/Black wire on pin 13) from the ecu and try it again. you'll feel a difference.

Mine has terrible take-off. Bogs down like crazy until 15-20 MPH then it really wakes up all of a sudden.

It's very rare that I can just punch the gas from a stop and spin tires (assuming traction control is off).

the 400s gearing really sucks on take off...once it hits 3k rpm, all hell breaks loose.

Red, how much did ur whole conversion cost? including the w58, pedals. etc.
