hello everyone! was wondering about some of your afr's for you setup... mainly looking for the gm stage 2, the 2.9, and the 2.8 w/or w/o 60's? me personally am running gm stage 2 and am running 14.8 crusing and 10.7 to 11.2 WOT . anyone else?

 

3" pulley on 42lbs gm stgII injectors, 84%idc, 11.5-11.8@wot, 14-15 during daily driving

 

intake or exhaust on that?

 

My old LSJ was 14.6-15.0 at cruising on WOT 11.9-12.0

Mods: 2.7, 60's, tune, meth, H/E, header to 3" d/p and 3" catback

 

KnN intake, pacesseter header(1.75" primaries), 2.75" catless downpipe, 2.5"od exhaust, 14" resonator, obx oval muffler

 

yeah mine is just the gm stage 2 and injen intake and gm sport catback

 

ur running rich right now, get it custom tuned and you should see a noticeable gain over what u r now...

 

well i hear that the gm stage 2 does run rich but i was going to put a 2.9 on with one step colder plugs and i was thinking that might just make it perfect or close to ... whats your opinion?

 

The car compensates for more fuel, if it sees more air...

 

with my mods i run a 11.8 afr at wot, the gm stage 2 tune runs pig rich, i ran a 10 flat at wot sometimes see a 9.8, you can easily run a 2.9 with that tune, just start worrying about heat, with my 2.8 im gettin alot of heat i really should be on meth

 

With the gm stage 2 tune, 2.9, and full exhaust I usually hit 10.5:1 WOT. With my mods now I'm tuned for 11.5-6:1

 

2.8, 60lb, 50/50 meth 11.0afr at WOT, 14-15 driving normal

 

12.2
