Went out for a short drive, had to wait for the cop to turn left & I went to the right on the highway 529, nailed it in 2nd gear up to 6100rpm seems to pull about the same, track time will be the tell, drivabilty is much better with the longer runner, the ECU did add about 11% more fuel in the WOT fuel cells 5000 rpm to 6100 rpm The length of the intake runner was 17" went to 24" to help lower RPM for a better 60' time at the track
