I have the FRPP CAI and Pro-Cal tuner. I also have an SCT-X3 with 3 Tillman tunes in it. Start this process with the factory tune back in the car. I have this idea which I think should work but I am not sure so I am throwing it out to see if any one says, "Don't do that" My idea is to use the Pro-cal tuner first to load in Fords 91 Performance tune which is required now that I have a their CAI. But then Use the SCT tuner to load in my Tillman tune which if what I am thinking is correct, will think that the Ford Racing tune is the "factory" tune and make a copy of it inside the tuner before over writing that tune with one of my Tillman tunes. The SCT would then contain all my performance tunes. The "stock" tune for the CAI would then be my emissions tune and the other three for what after market tunes are for. The Pro-cal tuner would contain the Ford pre CAI stock tune. So tuner experts, do you think that would work or is this one of those don't do that kind of things.
That is actually a good question I'ld be interested in hearing the answer too as well. I would say it should work being the FRPP is tuned to your PCM and the Xcal is tuned to absorb a tune from "your" PCM....... what came first the chicken or the egg??
The Verdict is.... In case anyone was wondering.... I went for it with my plan this evening and it worked. My SCT-X3 now has 4 usable tunes for use with my FRPP CAI in it. Return to stock will now load the FRPP performance tune which originally was in Ford Racing's Pro-Cal tool and is CARB approved. And the pro-cal tool now has the stock air box tune in it as it is supposed to. Now to return the car to the stock tune with the stock air box I will first use the SCT to return to "stock" then the Pro cal tool to return to stock.
