on a private track yaddy yaddy i did a small pull against a freinds bone stock s4. Well even before my mods I pulled on him and after my mods i ROCKED him even in boiling hot weather. The other night in 20 degree weather at 22 psi and holding we were dead even!!! what the crap is that?? my plugs are ok, my oil was just changed, the car feels good.

I have the stock headstuds and caught myself hitting over 26 psi when I was at the track a few times. Could I have lost compression or something? wouldn't I have noticed? because after that 26 psi run where I trapped 112 I turned it down and trapped 114 but what the heck????

My thoughts are...
- blown turbo (did go a lil while over my oil change but didnt drive it much or even hard much)
- stretched headbolts (but engine temp etc. stays fine
- mis-reading boost gauge
- pulling timing maybe? too rich? too lean? something with my tune that went outta wack. If I could show you I would but I don't have anything.

I'm just thinking maybe this might have happened to someone else I don't know but im positive its not a boost leak.
