While the 3.4 pulley did get rid of your KR, that was not your issue IMO. If you had no KR with the 3.3 if you did a pull from like lets say a stop to like 100, but you had it from a 30 roll and then it immediately went away, thats a tune issue. Invest in a tuner and tune your car. Obviously the AE is off since it only happens under certain conditions. A good tune will completely correct this issue IMO.
What is happening is you are at low RPM and go WOT and it jumps to full boost but the PCM didn't give you enough fuel, so it gets 7* of KR right then, and then you have enough fuel so your KR goes away. Set it so it sprays a little more fuel under those conditions and you will have no KR. Thats the best way I can think to explain it anyways.
You may be onto something Shawn. In fact it IS doing exactly as you stated. No KR if I take off from a stop but if I goose it at 30 mph, I get instant KR to 10*.
Temperature has nothing to do with it.
Maybe I do need those larger injectors.........or Todd, could it be as Shawn indicates simply a reprogram
Can INTENSE do this without new injectors.
If I do switch injectors, will the stock fuel rail adapt
