I have an XC2 I bought for my 05 F-150 w/5.4, now have an '08 with 5.4. Had someone else other than those used on this forum supply me with 2 tunes but I'm disappointed in the results. Made a big difference on my 05 but not with these tunes on my '08. I'd like an 87 tune for fuel mileage & one for the drag strip that is more consistant. Who should I contact for tunes? Thanks.
