[1 BAD BURB]

yea, thats about right. i ran 13.8 when it was bone stock. haven't had it back since i swap the exhaust...

one thing on these cars, the air intake design is horrible. there is too much engine heat from the top of the motor, thus heating the intake air. we need to re-route the intake such that it gets cooler air from outside.

thats a pretty good reason why your runs, consecutively, got slower...hotter air...
