you definately want the ecm rollback with a vxap2n2 strat. thats what i had and it made a world of difference in mileage

I have the VXAP2N2 strat as well, what is he rolling you guys back to for the best results?

not sure yet. just placed an on-line order a few days ago. there is a waiting list though(for remote reprogramming), so i am hoping it will be worth the wait. from what i have read, it will be....:D

tried talking my better half into taking a road trip to there shop, to have this done in person, it didn`t work. we don`t have passports, plus a babysitter for 4 kids....:doh:

on my 6speed its VXAM7QR. For autos i think the only change is the Q is a different letter.

Its well worth the wait!! :)
