Excuse the ignorance, but would using the BPBs (aka lengthening the IM runners) = a decrease in real world gas mileage?

Good question. I will be driving to WillowSprings raceway tomorrow for a weekend race which is a 3 hour drive each way. I will check for ya

Is there anyway to stop your ecu from learning without causing engine damage?

I'm expecting dynos @ exactly 10:31! You have 19 minutes. I am starting the timer.

Going to take a bit, shop is pretty busy today so I will spend about half the time tuning, half the time waiting and browsing the web for my friend to get back to the dyno. (Which I am doing right now *twiddles thumbs*)
