I purchases a used 07 Shelby GT in June from a NY car dealer. It won't pass NJ inspection due to system unsupported. They're saying the computer has been fried due to previous owner (or the dealer!) trying to alter the performance, the mechanic says i need a new computer which comes from Ford, then a program to down load the modifications from Shelby. It has cost me $500 just to find this out, now it will cost me $1500 to do the rest! I'm afraid this is going to screw up the performance and possibly the value of the car. There were SO many "warning signs" not to buy this car from this dealer....but i had to have "her"! Any suggestions? Should i go ahead with a new computer?

 

I would consider buying another used computer, have it flashed at a dealership to the stock configuration and get my test. Then swap back to the current one. Keep that other couputer just for testing.

 

Can't sell it the way it is so might as well fix the car. Six months down the road you will be smilin' because of the fun.
