Default hypertech power programmer problem?

I downloaded the Hypertech tuning into my practically stock 97 C5 A4 on tuesday morning. Nothing to agressive. Mid ranges on everything. I drove it all day tuesday with no problem that i noticed. Tonight as i'm driving up to the grocery store i notice that the oil pressure needle is buried. I check the digital read out and it is at 128psi. I stopped the car immediately and turned it off. The pressure slowly reduces. I just checked it and it is back down 92psi after being in the garage for 20 minutes. When i stopped the car i happened to have the programmer in the car and reinstalled the stock program. No change in the oil pressure problem when i restarted the car. I drove home with no explosions but.......?

Any ideas of what the problem might be?

It's not the HPPIII, it's your oil pressure sending unit. Easy fix behind the intake.... do a search.

1SLANDON; I noticed you have an A4. Just a note: the Hypertec will not do gear scaling on the C5 (though it works fine on F-Bodies).

Not a problem if you don't intend to change the rear axle ratio.
