Ok this is a quick update. Short version, I matched last years times on the same track with heavier rims and less sticky tires yesterday. This with cobwebs and rusty reflexes as it was first time back on a track since last year! Oh yeah that was with a bigger gut and 3/4 tank of fuel. https://www.nopistons.com/forums/pub...#>/biggrin.gif



Today, put the full race tire and rims on with better pressure advice and a little less rust in the brain and got a personal best time on a cold track.



Mike at Digital tuning.com has been awesome in support, and I'll be wringing another 5-7hp out of that little device in the coming weeks.



And It still blows peole's mind I tune it with my phone as well as data logging. https://www.nopistons.com/forums/pub...R#>/tongue.gif



Hard Data later but so far so good.
