Im going to take the SSTT out in about a week and clear the codes with a Bt scanner, if the limp mode doesn't come up its prob the SSTT, if it is what should i do? how would i have boost leaking?

I think you should be running low 13's with average 60' times with the SSTT. At least your runs are consistant. So you need to look at other reference points such as other 335i BMWs at that same track, same day. Or maybe get an accelerometer and see what range you are running in several different sample runs. On stock boost with good traction, low 13's are possible. As much as I tried, I couldn't get into the 12's on DRs with stock boost. SSTT or JB+ can get you in the high 12's with good traction.

Heres my stock boost runs for reference:

50F, 91 octane. 17 Kosei/Hoosiers

Run#1 DS Mode:
mile: 13.0 sec at 108 mph
60ft: 2.0 sec
1/8 mile: 8.4 sec at 86.2 mph
0-60mph: 4.6 sec

Run#2 DS Mode:
mile: 13.0 sec at 108.5 mph
60ft: 2.0 sec
1/8 mile: 8.4 sec at 86.9 mph
0-60 mph: 4.5 sec

Run#3 DS Mode:
mile: 13.2 sec at 108.2 mph
2.1 sec 60ft
1/8 mile: 8.6 sec at 86.4 mph
0-60mph: 4.7 sec

Run#4 DS Mode:
mile: 13.0 sec at 108.5 mph
2.0 sec 60ft
1/8 mile: 8.4 sec at 86.9 mph
0-60mph: 4.5 sec

Run#5 DS Mode:
mile: 13.2 sec at 108.2mph
2.1 sec 60ft
1/8 mile: 8.6 sec at 86.4 mph
0-60 mph: 4.7 sec

Run#6 DS Mode:
mile: 13.0 sec at 108.7 mph
2.0 sec 60ft

I wonder if 93+ octane fuel would have helped get you in the 12s?

Nice times though, you are very consistent. Did you brake boost at all?
