Setting new TPMS values
I'm running NT05r and the car needs to run a lower tire pressure then the factory calibration.
Since the tire pressure is under 25psi, I'm getting low tires pressure. Is there a method or has someone reprogrammed the BCM to adjust that number? I'd like to make the car think that 20psi is optimal and 15psi is "low" and 25psi is "high" or something to that affect.
Please, do not preach about tire pressure and what GM says and what the tire says. I really don't care. I'm just looking to understand if I can tell the computer what I want it to run with.
Removing or disabling TPMS is an option I suppose, I'd like to avoid that if possible, it's nice having the read out.

Put all the the TPMS is a canister/PVC tube/pipe/etc and pressurize it to 30 PSI.
Old track trick.
Of course you won't have sensors in your tires, but that probably doesn't matter for whatever you're doing.
