Are there any gains in throttle response by setting the tps in different places? What do yall recomend for the base setting?

1989 Iroc-Z TPI 350 auto 4-spd Removed MAF screens K & N filters, stock other than that.

 

With the ingition on, not with the car started, it should read inbetween .45 and .60 volts, mine is set at .55 volts. The max reading at WOT should be at least 4.0 volts.

I think that I have better throttle response when I set the TPS voltage on the high side, such as, 0.62V, where it is now. I have had the TPS as high as 0.67V with great response and no error codes.

As mentioned above, set the TPS voltage with the key on and the engine not running. Also, at WOT, the TPS should be above 4.0V. Mine is at about 4.5V at WOT.
