AIS methenol kit non progressive, line pressure at 160-175 pump turned all the way up from ais, 6gph nozzle located in a tb spacer (<---very important) 75-80% pure M1 methenol with distilled water.

Really .... only a 13.5. Does he have any traction mods ? I heard of guys getting 12.9's on this setup . Must be with only drag slicks then .

people say it runs leaner than stage 2, but is that when the high octane mode or nitrous mode is engaged ?? it is to my understanding that the GMS3 tune is identicle to the GMS2 tune when you arent running high octane mode or nitrous.

i have to clarify this though .... there is no GM Stage 2 Tune. GM Stage 1 & GM Stage 2 come with the same tune .... So really there is the GM Stage tune for Stages 1 & 2 & the GM Stage 3 tune. I know its easier to just call it the GM Stage 2 tune, but when new people come on here they get confused by the diff. tunes out there.
