    High TPS volts?

    On my procharged 2000 Z28 (with built top end, aggressive cam, etc.) I'm getting high TPS voltage. I can get the TPS to read at 0% but the voltage is around 0.8, when it should be in the 0.4 - 0.6 range. Any suggestions?

    What TB are you using? I have an aftermarket 90mm TB and I had to slot the holes to get voltage and % in check.
