maft settings on a 5177 dry kit?

I am just curious to see if anyone can post what maft settings they run with a dry kit, mainly their WOT setting. I know I am rich with my LT headers already as my o2s were at 930 ish, and being a 98 will make me a little rich too. I am just wondering if anyone changes their WOT setting at the track when they run the juice and how much. Any help will be appreciated! Thanks in advance.

Depends how much you are shooting and what is your base AF/Timing*

On a stock tune ~12.8>13/28*, you do not need any wot change untill you go over 125 shot dry. with 93 octane of course.

A diagnostic device, Atap, EFI live, Hp tuner is a must for N20 tuning.
1- determine the limiting power range of your fuel system for your setup.
2- Start small and go from there while watching AF/timing*
3- What works one day doesn't necessarily work the next as far as tune is concerned.
4- A little richer is always better, so with MAFT, know your base tune #'s and adjust for a tad richer.

Thanks for the help guys! I will be watching with a GM tech 2, I tried the 85 jets last night and it went good. I went (to be safe) from -6 on the wot setting which got my o2's to 890-900 and bumped it up to +4 when I sprayed. My timing before would top out at 26 wot so I think I should be ok. The black (rich) smoke behind me gave me a little more confidence. I will put the scanner on it next time.
