Bootmod3 Stage 2 93oct
ARM Catless DP
Muffler Delete
Tried a ~20% E85 blend
Went to 1/4 track and best time was 12.822 @155MPH, very disappointed.
Somethings gotta be up right? Used launch control every run and I consistently ran 12.8/9. IAT's were constantly 40-50F above ambient (80F) and it was very humid outside. I dont have any proper logs but according to Bimmerlink I was hitting 19psi max during the run. I'm gonna build a custom intake and hope that helps for next time :\

Is your 650i RWD or AWD? The trap speed looks good though |
RWD, used stock launch control at 2,000 rpms on street tires. Almost no spin off the line and throughout the run. Ran 12.8/9 for 5 runs.
I feel like the car isn't performing at its full potential due to weather or something. On paper these run 13.1 stock so it's hard to believe that BM3 Stage 2 only improved it by .2-.3 seconds when I'm seeing a bunch of 550xi's run low 12 high 11 with same mods.
