Does this help raise that 4 psi mentioned in the other thread? I should add also that there is a white mark lining up the actuator arm male/female ends. You can see it in this picture as well - if you do adjust the actuator, make sure you align the marks when you re tighten the actuator arm nut so you do not raise suspicion at the dealer - I presume that is why the mark is there in the first place.

Thanks for the sweet info! i will be trying this tomorrow hopefully.. I have a boost gauge hooked up in my car so i will let you know what the difference is when i do it! unless someone already does.. And ya i am pretty sure that mark is to tell them if you have loosened the bolt at all so it may screw with your warrenty so id make sure to line them as best as possible!

I did mine and the first time went two full tuns. This was too much as the ECM would try to control the extra boost and it would be jerky.

One and a half turns is great. Especially in the lower gears where the rpms rise so fast the ECM cannot compensate fast enough.

The paint marks are on both sides of the nut so it is still easy to keep looking "stock".

Thanks man for the info - I will give 1.5 turns a shot when I buy my CAI.

Anyone have any problems removing any of the bolts/nut?

Everything came apart easy but the car only has ~2K on it. I did use some copper base anti-seize when putting the bolts back in.

The difference will be almost negligable & you really have to be paying close attention with your butt dyno, plus know your car's performance very well prior to the mod to be able to tell a difference. I noticed a light jump in torque in lower rpms & the car seemed to hold boost slightly better, but that was it.

Any time you turn up the boost without knowing what your afrs are is just asking for trouble messing around with the boost levels is not something to mess around with unless you know what your car is doing.

Changeing boost is like adjusting timing ect to much and not adding fuel or pulling timeing can make your engine go boom!! i wouldnt raise it any more than a couple of pounds if any. Hopefully you guys are useing some kind of logging software. ( DynoJet CMD) or other.
