Your best bet would be to redo the gears....its night and day difference. The tuner would be able to change your speed and shift points and get you a little more power, but you are still hurting your transmission.

Well i emailed SCT and they replied today and said that you can turn it off with the custom tuning but they recommended to use the buttons on the truck just to let you know.

Thanks for the advice. My plan is to regear, possibly to a 4.56 ratio. I will then get the programmer to make sure I am not running to lean with the catback system and CAI.

I have tried to turn it off manually, it doesn't really work. I think it is the RSC that turns on. It happens mostly when I am making a left hand turn at slow to even normal speeds. The truck cuts power and taps the brakes. It is really annoying. My local ford dealer said it was due to the larger tires, the only way to prevent this is supposedly to remove the fuses!

I was hoping I didn't have to resort to removing fuses due to loss of ABS and the annoying warning lights on the dash.

How quickly will the SCT upload new programs? For instance, switching between an every day driving program and one to tow/haul something? Would it be easier with the edge?

It usally takes me about 5 mins to change between tunes. I was running a 91 performance and switched it the other day to 87 performance due to the raising gas prices.(and the fact that everywhere around me is 93 octane and i accidently ordered 91 octane:doh: so i choose to be safe and run the right octane. So be sure to get whats around you.)

I have 87 and 93 octane. Is there anything special I should get for the programs? How long of a wait was it for you? If you don't mind me asking how much did it set you back?

Im not sure what you mean with anything special with your programs. if you are talking about what tunes i have a 87 and 91 performance and 87 tow tunes. The wait was about 2-3 days for my programmer then about another couple of days for the custom tunes since the x3 doesnt come with canned tunes Bill gets the x3's tunes first or at least sooner. It costed me about 430 dollars for the programmer and 3 custom tunes. Which actually saved me money since i had the money put back since december for the Edge CS and CTS.

How happy are you with your purchase? Have you had a prior gryphon to compare it to? Have you seen any mpg increase?

I'm extremely happy with it. No I haven't had a previous gryphon but I had a bully dog programmer for an 07 and the SCT with custom tunes makes it look like a little puppy. Also I have notices close to about 2MPG increase.
