  1. My 2008 Gt500 has brand new Nitto tires, stock size front/rear. I'm thinking of changing rims to a retro 5 spoke. Mickey Thompson has one that will fit, but it only comes in 9 and 10.5 inch. I'd like to not buy new tires. My car has Eibach Pro Kit lowering springs on it. So my question is: can I put my tires on a 9 inch front and 10.5 in rear? What kind of height difference occurs from 9.5 to 9 and 9.5 to 10.5? Thanks, Brian
  2. Thanks. Bama identified FBMM0C9 as a stock Ford tune. Stock as in that's what came out of the factory, or stock as in standard modified configurations?? That hit their intelligence level. I have read that Ford may put the stock tune back in during routine maintenance, so that's my concern. I think I'll go ahead and pull a spark plug to see what's in there and then go to your recommendation for a tune. If you ever watch the GT500 build on Americnamuscle.com, the previous owner seemed to have followed their recommendations. Thanks again.
  3. Hi: I bought my 2008 GT500 used last year. It already had a JLT 123mm intake and 2.6" upper Supercharger pulley when purchased. The Carfax shows that the car was serviced in 2014 and the computer reprogrammed at a Ford Dealer in NC. I bought an X4 tuner from SCT and asked for 2 Bama tunes with the criteria based on what mods the car has on it; a 91octane and a 93octane tune. The car won't run on either tune. It barely idles and acts like 4 cylinders are dead if you touch the gas. Here's my dilemma: the Bama guys want to know what my "stock" tune code is. Since the was reprogrammed in 2014 I don't know if what's in there is stock or not. The code is FBMM0C9. Bama told me that is a stock Mustang code. Can anyone tell me if it is a stock code and would Ford modify this code to accept the JLT and pulley, or would they put in a different strategy? I want to make sure I'm getting all I can out of the mods. It doesn't sound like it, but for arguments sake lets say the car also has cams in it. I don't know if that is addressed in the FBMM0C9 code and it is certainly not addressed by Bama. Any information on the FBMM0C9 code is much appreciated.
