2008 Corvette LS3 Auto 6 speed
Car only has a Cam 225/230 113 LSA new springs and rods.
Factory NPP Exhaust w/ Factory X Pipe
Got a Mail order tune that wasnt to par so my friend and I began to work on everythihg.
Car is still running very rich at WOT low to mid 11's AFR
in Open Loop it is rich under 2k RPM too.
On my scanner I see a lot of knock retard
so my friend and I tried to lean her out and couldnt...
we adjusted the MAF table and VE table and it didnt make a difference.
How do I lean the car out so I can get my 12.5 AFR at WOT.
Thanks
