Get a stand-alone and program it in.

The ECU controls that air/fuel ratio. If you want to lean it out, you will need to reprogram it. If not and you try other ways, the ECU will constantly attempt compensate.

why do you want to do this?

Man, you sound like my mother. :-)
If you lean a bit your mixture you are adding some free HP.

Just don't melt anything

Im just wondering because i put my car on the dyno and i was at 12:1 all the way to 7500 redline and that is optimal. So leaning out the mixture can be dangerous

I tought the ECU would read that, and set
my mixture rich anyway. But now that you
mention i guess your right.

Thanks.

No extra power, just that the car will run properly.

Here is more info on the TPS adjutment. Your setting should be between 0.45-0.55V.

0.58V might be too high. Just get it below 0.55V and you'll be fine.
