Well, the tire on the Z51 car actually has a UTQG wear rating of 220! Good, a soft tire for once on a Corvette that will allow good traction and performance; drop some pressure and it should accelerate well too. This soft tire was probably a mistake by some bean counter. I have not been able to find a softer tire to date.
I am led to believe that if the computer senses a low tire pressure it greatly reduces the available power to the driver. (More of the gov't or some ins. co. protecting us from ourselves)
I am also led to believe the magic number is around 22psi. Gee, just where I would put the pressure for the strip. Is there anyway around this at all?
Lastly, can the damn sensors be ditched or will the ECU/PCU or whatever it is called, have a fit and prevent the car from running properly etc?
I would dearly love to get rid of these things ASAP.
Anyone out there really know what the story is on this TPS unit?
Thanks for any input.

OK. In response to a previous thread about TPS sensors and what happens if you dont have them.
I mounted a set of aftermarket wheels and the FRONT wheels could not accept the TPM sensor (long story, don't ask).
So, until that problem is resolved, I'm driving the car with only the rear 2 TPM sensors.
Here's what will happen:
DIC displays info that the tires are flat, and not to exceed 55 mph.
The Tire Warning idiot light stays on.
You are not able to change to "Competition Mode" or turn off Active Handling.
Hitting RESET to remove the warning from the DIC only works for a minute before it displays again.
The tech at the dealer is pretty sure the monitoring or the display of the monitoring can NOT be turned off. He will look into it but we're both doubtful.
If Boyd Coddington cannot come up with a suitable
workaround to installing the sensors, I may be forced to build a teeny tiny tank, install the sensors to it, and pressurize the tank to 30 PSI.
By the way, on my C5, I had the sensor warning come on after starting the car after leaving a movie theatre. To be honest, I don't remember if I drove a short distance before it came on for all tires. I thought somebody slashed all the tires.
I couldn't see any physical damage. When checking tire pressure, all tires were below 25 PSI. Went to a gas station to raise the pressure to about 32 PSI to compensate for tire heat. Started the car, drove a short distance and everything was fine.
This occurred when the winter season was just starting and would get fairly cold at night, about the time we left the movie theatre. I am sure this caused the low-pressure problem.
