how about just buying one? You will be in trouble if you 'loan' it from a friend, run into problems, then need to borrow again to re-tune. Just purchase one and call it a day


Well thanks I already thought about that, but whats the sense in spending $400 to buy one to tune the car and put it a drawer in my tool box and never use it again. Thats why I was looking for someone that already had one.


Ok guys just bought a SVT tuner for my 04 Grand Marquis. Looking for someone who has a tune other than the one that comes already loaded in it. I tried american muscle but they want $150.00 for even just 1 tune, I can't see changing the tune that often to pay that kind of money. Can anybody out there help?

If you really want to "get it right" find a speed shop with a dyno and have it dyno tuned.
