I ran the ACE with flex fuel and 7800 rpm redline, and am running JDL on 93 and 7600 rpm redline. No dyno graphs to compare as the current tune was done remotely. But overall the car feels awesome again, very peppy and sounds much better too.
Last time at Barber in July on OEM tune and exhaust all I managed was a 1:50, last Saturday I was doing 1:46 (also running sticker tires though) and was hoping for a 1:44-1:45 Sunday morning but that will be another update as to why I did not run Sunday at all.
