Did a few things recently,
Purchased a SCT programmer with custom tune from LaSota Racing. Did some UN-scientific testing and gained .6 seconds in the quarter and about the same 0 to 60 MPH. If you do a search for drag racing calculators and enter the increase in MPH it gives about 12 HP gain. The most noticeable improvement is during spirited driving, it is much more responsive and just seems to run "right". Before it always felt doggy in the mid-range.
It is still TOO slow and I'm accumulating parts to fix that!
