If you can find someone with HP Tuners they can adjust the tune in the computer and you don't have to worry about a different regulator

The SAFC was tried on out cars, and it did not work. The PCM is too smart for it and overrode the SAFC in the end. You will need to buy HPTuners and a laptop to correctly tune your car. You can also purcase a tune for $100 (send in your PCM and they send it back) from a vendor to get you started, or borrow a tune from someone on here via HPT. An adjustable fuel pressure regulator is not an acceptable way to tune a car either. It's more for a fine adjustment to the fuel system.

also a bad idea to be borrowing tunes from other people, again the FPR is not to tune but to get the right mix of A/F, sorry if it came off like i wa going to use it to tune.
thanks for the info and feedback

I meant to use someone else's tune to get you started. You could also give TAG racecraft a call. They can do a mail order tune, that could be tailored on the safe side still until you get hooked up with HPT.

Better off finding a member with HPT near you in Texas and having them hook you up with a tune.
