well i upped my boost to 10-11 psi and now the car does not hesitate nealy as much, throttle response is way better and it seems much faster even before i start to hit boost...why in the hell is that? it does not make any sense to me what so ever...I put the boost down to around 8-9 again and now it hesitates and feels soooo much slower..any ideas guys?

Thanks,DJ

P.S

Im going to get the timming done and front mount put on this weekend so that should help in determining if its one of those 2 issues...but could it be the actuator that is the problem?

Your fine up to 12psi on a SMIC. I ran mine that way for a good 3 months before going FMIC. Id say the hesitation could be from timing or fuel. If timing is set right then id check fuel pressure. Stock is 43.5psi so set it near that if its higher.
