Hi everyone, hopefully someone can help shed some light on this for me.
2011 Z06 Z07 option.
Procharger w/ D1SC and 5.00" pulley for 5psi
B&B headers w/ highflow Cats.
Injectors I found out are 65lb FAST ( and see they are not good from searching on here)
I have the PE set down to 11.2:1 and have the MAF scaled to less than 3% error around town and highways cruise. Driveability is like stock.
I am attaching the present tune. I can also say I do not know how the car ran previously to this install, but was told it dynoed 470 rwhp on a Mustang dyno.
The car has been previously tuned NA by another source and is now brought to me with a procharger installed.
My problem is this, stab the throttle and it cuts out, lean into it and no problem. Not sure what I am missing.
Second, no matter how much I throw at the MAF for fueling I am going lean! Drops down to 12.0:1 then bam climbs to 16:1 in a second. I am including the tune and any help would be appreciated.
This is my first Boosted LS7 and maybe I am missing something glaringly obvious. I have tuned boosted cars and now????
Okay, Now I have codes P 0101 and P0121, I was under the impression that VE tables do not need to be done on the LS7, apparently that is wrong? So, do I need to do a virtual VE table to adjust so the MAF and calculated air flow match approx?
