motor is a b18c gsr with a t3/t4 turbonetics turbo. the motor seems to ALMOST die out on me while trying to get out of first gear but this happens AFTER i run the car full throttle through 1st, 2nd, and 3rd gear then i would have to turn off the car and everything would be running perfect again. when i drive at cruising speeds (with out running it full throttle) it runs normal. any suggestions? thanks in advance!

 

anyone?

 

More info needed.. What are you using for engine management / fuel management?

 

i got a stock p72 ecu with a vafcII. I up'd the wide 12+ and the narrow 7+ to give it more fuel since im running with the stock fuel pump. i just got the turbo on this past weekend and im running uncapped from the turbo down pipe since it cant reach my exhaust pipe (i have to take it to a shop to get it welded) and right now the o2 sensor is not connected. could that be the problem?
