Finally Supercharged

so my supercharger is finally on and running, i got it to around 11psi but its raining out so i spin the tires at WOT in 1st 2nd and 3rd haha.
my only issue is that at idle my afr is perfect 14's but when i go into boost it goes to ~8 so I'm running very very rich... could this be because of the tune (trifecta)? I'm going to give Vince a call tomorrow.

seems like you have an NA tune?
8 is really low, i think 11 is ideal for boost, 14 for na

I heard some others say that with the tuning and bolt ons, they had to drive around a bit for the computer to settle things.

Maybe it is true in this case.

innovative LC-1 wideband...
maybe its a bad calibration? that doesn't explain why idle is normal though...

the lower the number the richer your running..the higher the number the leaner you are then something will blow... at the most when your rich it will smoke black..

Sounds like you should have calibrated your LC1 before you put it in. I wouldn't entirely doubt it, but 8 at WOT is extremely rich. 14 at idle is in fact perfect. Good luck.

its cause im tuned for lsj injectors but the guy sent me stg2 and didnt tell me they were stg2 injectors i use an 1/8 of a tank in 30 mins of driving haha

also running too rich wont blow anything... (i'm pretty sure) its lean that is bad
