I purchased the 2fast2furious tuner kit w/ the 3.4 motor but this motor is performing horribly. It seems to be getting no torque at all. It takes about 3-5 seconds to get moving. In that 3-5 sec. it has little spurs where it will move about 1 cm. It will do that, then start moving slowly up to its top speed. This motor also cannot reverse without a push from someone. The top speed of the engine is slower than that of the turbo/2.8 motor. Does anyone know what is going on and what i can to to fix it.
