S550 Power Packs

I'm considering moving into a 2017 GT PP car. I have talked to the dealer about getting one of the Power Packs (Stage 2 or 3) as part of the deal. I figured it would be a good way to get some extra power right out of the gate and still have full warranty.

I was wondering if after having the Ford tune put on can another tuner be used later on if I wanted more changes? I was thinking down the road I might want something like a setup to run E85 or install a full exhaust system. Is it possible to even make small changes like if you put different tires on and want to adapt for the size? I also thought it would be nice if you could change the amount of air pressure the TPMS system is looking for. Though I've never heard of that last one being done. It could be a useful tool on a track car where we air down the tires a bit since they come off higher (and hotter) than when the session started.

Yes, you can put a different tune in, I'm sure a different tune can squeeze about a few more hp, I'm guessing 10-15 tops.

With any of the FR power packs 1,2 or 3 you have to revert back to stock to do a different tune. Even between fords power packs you can't go from 2 to 3 unless you buy PP3. The Ford PP are specific to your car because of your V.I.N. # and cannot be used on another car.

I've read that with the PP2 or PP3 which use the GT350 TB they work great with the Ford tune but other set ups have had issues.

The TPMS just reports back what your tire pressure is. You can't change the pressure without manually deflating or pumping air in.

What I asked was if you could change the amount of pressure the TPMS is looking for. Obviously it can't inflate or deflate your tires. I presume the TPMS is set to look for a range of air pressure in tires. So if the recommended tire pressure is 32 it probably alerts if it drops below 30 or something like that. When going to a road course track day (with certain tires) it's better to start with a lower air pressure and then aim for a target "hot" pressure when you come off the track after 15-20 minutes.

You can't do anything with the TPMS because they work through the BCM, not the PCM.
