Default Stock 2002 Z06

My dad has a stock Zo6 and wants to keep it stock. Alot of people have told me the stock tune is pretty conservative. We are at about 5,100ft in elevation. How much power could he get from a dynotune?

Hard to say, but on mine I do notice mine is running about 12.2:1 AFR and only 22* timing. Should be at least 10rwhp to be gained on 91-93 octane.

It is just a wild guess. You might try doing a search on the CF forums.

I was guessing that too, but hoped someone with a baseline would chime in.

You could probably pick up 10-15 RWHP with some tuning.

Though the 2002 Z06 timing curve is considered somewhat 'conservative', the real gain in any tune lies in properly attaining the correct AFR for maximum power. I.E. 12.8-13.2 at WOT.

A tune would ensure that under WOT the engine is not overly rich (or lean), and perhaps some additional gain could be made in enhancing the timing curve.

If you have the extra bucks to tune it and someone is capable and willing to tune it properly, it is probably worth the money.

Good luck, it is a nice car even 'just stock'.
