lol, yeah... I had a 3" turboback without a boost gauge and I was proabably boost creeping up to like 15 psi... I fried the bearings in my turbo and haven't driven it in like 3 months... porting the wastegate is a must.

btw... stock boost is 5.5 psi for S4s, 7.5 psi for S5s, and 10psi for FDs.... I don't know where you were getting all those other numbers....

 

well that all makes sense. Maybe my boost gauge wasnt right when it said 13 psi. Its just odd though cause I have not added an fcd yet and it has never hit fuel cut to this point. WOuld that be possible??? Becasue I know a few of my warning lights are disabled at this point because I can go(or could before exhaust) go past 7k without hearing a buzz or the light going on. Also there is a wire on top of the radiator that is not plugged in and I know it should buzz if its not plugged in. I dont know when I will have time to get that turbo off. i guess till then I have to keep a light foot.
