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?
