i heard somewhere that your throttle position sensor must be set at the correct volts for maximum horsepower. does anyone know the correct volts it must be set at? if you do i would really appreciate it.

Tech articles off the main page has a complete "howto"

i looked all over that page and i couldnt find it so does any one what are the correct volts my tps should be set at?

It should be .54 +/- .07 at idle. The tech article he's talking about is at https://www.thirdgen.org/newdesign/tech/tpimod2.shtml and here's an old post. https://www.thirdgen.org/techbb2/sho...ight=tps+vader The last post by vader is the most informative.

Hope it helps.
