niic Member 7 Member For: 14y 8m 8d Gender: Male Location: SA Posted 12/06/12 12:01 PM Share Posted 12/06/12 12:01 PM GdayI had my car tuned approximatley 6 months ago and ever since I've had issues with the tune.2008 FG XR6T AutoMods were:PW Stage 2 IntercoolerBosch 42Lb injectorsActuator'X2' Flash tunerXR8 Intake scoopHigh-flow catAll of these parts had previously been fitted to the car for a previous tune (with the exception of the high flow cat), and were taken off the car before I bought it. All parts were re-fitted and a new tune was done. Stock everything else, ended up at 297rwkw.Just prior, I fitted 6pot brembo fronts, left the rear stock.Now, the issues I face:1. When I start the car up, it runs fine. However if I put it into either drive or reverse without leaving it idling for atleast 30 seconds, the car starts to shudder/rock similar to when a car drops a cylinder or a coil dies. Revving the engine ceases the shuddering and at this point I usually drive off and dont experience it again.2. Also, when going from periods of long high-way driving to slowing down and braking to a halt, often the revvs drop completeley and the car stalls (its an auto).3. This stalling when halting also occurs during normal driving, and I have noticed an increase frequency latley. Driving in performance mode decreases the frequency with which this occurs, however when coming to a halt, the revvs will often shift up and down for a few seconds as if trying to find where it should be idling at.4. Finally, when flooring the car, how it performs doesnt seem right (disclamer: I havent owned a turbo vehicle before so Im not 100% what is should run like). If I floor it, as it gets roughly 2/3 through its rev range, it seems to pulse. I can hear the turbo/injectors/whatever going pssst pssst pssst pssst as if hesitating. I imagine it should be a long smooth increase in pull and boost before the car changes gears.So yeah, that's about it. Any ideas as to what could be the problem please send it my way, I want to gather some corporate knowledge before I take it back to the people who tuned it.One other point, I was initially unsure of what the injectors were, however were told they were 60lb injectors. So that's what I told the guys who tuned it. Would there be issues here? The blokes tuning it thinking that they had 60lb injectors to use but instead had 42lb injectors?Cheers!
