I'm new here and I've been reading some threads on the Bob Jusnes and FordChip re-tunes. What are the warranty ramifications if you use one of these tuning programs. I assume you "return to stock" before you take the car in for service. Is there anyway for the dealer to know you're using a flash tune. Also, will these tunes help with normal, around town driving or is it only at WOT. I'm an old guy that just wants more response and power, but don't intend to bang my V6 off the rev limiter all the time. Thanks

Well, I know with the X-cal 2 you can store 4 tunes, your factory tune that the car came with, then 3 other "performance" tunes. That way, when making a visit to the dealer, you just reflash your computer back to the way it was when you originally bought it. I dont know if it dates the flashes in the computer or not, but that was the way it was when I had an X-Cal 2 on my 99 F-150.

Thanks for the info. I can't think of any reason why I wouldn't reflash before taking into service. However, I'm more concerned about a situation like the alternator failed (happened with a previous Ford) on the highway, and I have it towed to the dealer. A situation like that is my biggest concern. Thanks again

The tunes definitely help at all throttle positions not just WOT. Tip-in response is one of the biggest improvements on ETC cars like yours.

The computer will record an "event" when flashed. It does not specify if the event was a reflash or simply a code scan. Just going to AutoZone for a code scan would trigger the same type of event. Scanning for codes is not a warranty violation.
