I have an 06 with Paxton that ART installed in TX. Upgraded fuel system bigger injectors dynoed at 650rw but leaned out at 4100rpm to 12.3. Just a little nervous about 12.3
NO that was the leanest it got. Riched up in the high 11s on past 4100rpm.
No he didn't and didn't find cards.
Dynoed in Smyrna Tn at Performance Garage
No leads in this area. I will call him tomorrow and see who he knows.
