I just recently installed my custom tune with my sct 2, now the stang takes off slow and when it hits 2000 rpm it really falls flat on its face, like its not getting any fuel, all I can think of is when I ordered it I said a later mod was 4:10 gears, but I still have stock right now, who do i contact to get a xtr file to modify?

When I put it back to stock, it runs fine

 

I believe you can change the gearing yourself. You go to someting like change paramaters, and look for gear ratio.

 

Yeah, I think the gearing only applies to the speedo. I don't think it affects the actual Air / Fuel / Spark parameters. You can change the gear ratio yourself as stated by blownstang. If it works with your stock tune, then its definitely the tune itself. I would contact the dealer that tuned it for you / sold it to you. Or go on www.sctflash.com and post your issue on their discussions board for assistance.

 

Thanks Guys, I have Nick at American Muscle working on it as we speak
