How big? You might not need to pull timing depending on how small you are going. Just change the PE I guess.
Wet is easier to tune, imo.

He's running a beefy cam and over 30* of timing on an IFR/PE tune. He'll need to pull timing. How much timing and where along with adding fuel (and where to add it) is what he's asking. :)

Esh! I run more like 19 degrees just to be safe. 30 is too much unless its low compression motor.

You can tune at the track easier with wet. Just change the jets; no laptop.

Make sure you're logging GM.CYLAIR_DMA if you're running the MAF. GM.DYNCYLAIR_DMA is for speed density (MAF disabled). :)
