Too hot, still slow.
Got some passes in at QCR today, T&T, hot and real high humidity, AIT peaking 177. 41psi pass bleeding off bad to 35 with **** poor boost response between shifts, im blaming my boost controller set-up, MBC to the bottom port of the Tial, what seems to be happening is two things, back pressure in the exhaust housing is blowing the WG open early and running the MBC to that port is not helping matters. I need a good EBC to run off both ports to hold more boost and give me more response. Best ET was 10.267@140.53 on a 1.53 60ft, best MPH was 10.367@141.76 on a mad spinning 60 of 1.616(no way around the waterbox). Stay tuned for a boost controller fix and a cold night at PRP on the 29th.

Are you still in 4th gear at 9k for those runs or are you shifting to 5th or have you lowered you final drive ratio? Nice times though... you really need a track that will give you the traction you need. Nighttime will also help
