there is a few changes in the setup, this is on a 1.32 turbine with a bullseye race cover for the s475, i had the old cover with me but as always we didn't have time to compare the two..

i was at the track 2 weeks ago, got 1 run and the car leaned out badly for no reason, ran great just a few days before, then it started to rain so we went home.
was out yesterday and still has this issue, it runs great in vacuum but leans out 15-16AFR under boost. havn't had time to check but feels like my FPR wont compensate for boost..
here is a recent pic of the car

15 to 16 AFR? That is seriously lean! I am happy that your engine didnt go at those AFRs! That could have been very bad!
Glad you found the problem early before the engine went, although I would be slightly worried that there may be some slight damage to it! Hopefully not!
This highlights the importance of a AFR gauge!

You may want to varify the accuracy of your a/f gauge on a dyno with another gauge. Your sensor may be bad. Thats very very lean not to have had your motor damaged, if you were under boost.

i always have my left eye on the gauge so when things go in the wrong direction i take my foot off the throttle.. This happened at the strip and i had alot of other things to think about... only ran first gear before i noticed.. it started spitting in the exhaust.
motor still runs great so wont open it before it dies 100%
