I have a vortech supercharger with the 3.12 just had it street tuned it runs great but i have noticed when i hit around 6k rpm and up it leans out a bit.. it seems to be a solid 11.5 up to about 4.5k then it slowly climbs to 12.5 around 5.5k and hits 13.6 by redline.. is this too lean? i just dont want to damage my engine.. my tuner has tuned several vortechs and said this is pretty typical for them at our altitude (mile above sea level) and wont cause any damage.. i just wanted to see what everyone else has to say..


*** if anyone has a fuel map for a ssbox that they can load or email me to compare to mine i would appriciate it.. cheezit81@hotmail.com Thanks**

 

Yes.. you need to get that check out. At WOT I am at 11.2 all the way to redline.

 

Your tuner is F***ng IDIOT!!! If that is my tuner I would've demanded my money back and kick him on the FACE!! I'm not kidding!!! This really get my blood boiling!! So you tuner only did street tuning and not on a DYNO? What injector do you have? Maybe your injector is maxed out and couldn't give anymore fuel up top. Or your tuner is just plain IDIOT and tuned it that way!!!

 

it was only street tune thats all i requested i didnt pay for a dyno tune.. its all stock just the basic vortech kit with the fmu.. it was running rich as hell before like 10.0 all the way to red line so i dont think its maxed out.. he is a good guy and knows a lot about the z platform ill probably just go talk to him im sure he will mess with it to get it right..

 

waay to lean..it should be low 12's in the lower rpm's and then around 11.7-11.8 in the higher rpm's to redline in the mid 11 range...

 

make sure the inline pump is coming on correctly..it is most likely just a tuning problem as the tuner seems like a moron who knows nothing about F/I tuning

 

ok thanks thats kinda what i was thinking.. im gonna go talk to him and see what he can do..

 

can someone with a vortech kit post some pics of their fuel map for the ss box? i pulled mine up and i would like to compare them just to see where mine differs.. i know they would be the same but i would just like something to reference..

 

 

does anyone have their split second maps?
