Wastegate Arm Adjustment

Ok, I was on another WRX forum and alot of ppl were talking about doing the wastegate arm adjustment. They said to take off the C-Clip and losen the 10mm nut and tighten the arm 1-2 turns. Seems to solve wastegate flutter when using a catless DP and 3" exhaust and you might get a few more PSI. My 07 is running an Invidia Catless DP and Invidia street exhaust right now. I have the factory boost gauge and it only seems to read like .6-.7 Bar. Thats only like 9-10psi when I thought stock was supposed to be 13.5. Anyway, I read that tightening the arm 1-2 turns will raise boost a few psi and hold it longer.

Alot of ppl were saying running catless DP causes the WG to open too soon and boost to fall off and/or be lower than it should. So I thik I will try this mod.... any other opnions?

Get or drill out the restrictor pill also helps with that. They discuss this in the Cobb forums if you want to search on there.
