[Northern X5M]

I finally got to the track with the BMS set to 3.0 (94 Octane) and Gruppe M intake installed.
It was so hot and humid I considered not even going. 25C and +80% humidity. Most of the night, the air was high 4000s and a guy with a weather station said the air broke over 5000. But with posted weather numbers I could only calculate high 3000s to low 4000s.

I figured I would still run better with the BMS set at 3.0. But all my times but one were the same or slower than without the BMS. MPH were all 119-122.

Main thing I am now finding is off the line the car will lurch forawrd then hesitate then take off. It isn't a bog but a definate hesitation after the car starts to move. Anyways, I have been using Drag Times to standardize my runs; even with the crappy air, my car was about .1 faster with the BMS. My low trap speed still is a disappointment for a CP car. I am hoping this increases in the fall when the air drops to low 2000s.
