So after 4400 it pumps to a flat 10. Here is a SS with log tracer. Anyone see something I am not? Other than the AFR target hits the end of the screen which is strange since the other graphs seem to be normal . Walk in WOT This was just to about 4000, nothing special to see after that. It seems in that midrange that there is alot of air noise in filter box, the kind you get with a stopped up cat. It just seems flat. The Correction trims stay at 98-110 at any given range/ load. On wot they are stuck at 100%/

I would love some input here. I need to fix this before I pull the heads and do some more mods. I am ready too just need to hammer this out first.

07 2wd non flex
90mm LS7 TB
Airraid CAI with restriction delete (K Fuel multiplier Set to 38004)
long tube headers with B1 o2s in front bung
dual straight pipes w/no crossover.
E3 plugs
injector filter delete
Trutrac w/ 3.3

Do you have the tuner version of uprev? never seen the fuel schedule on my version before, but haven't really looked at much besides o2 and other parameters.

Hi, I do have the tuner version and it is the newest release.

I kinda wish they would build some kind of fuel map auto trim learn where it adjusts and smooths automatically . That would make life so simple :)

Ancient thread but yeah you needed to compare your MAF voltage at 4400+ with a stock or another VK56. You also didn't include your timing map in the screenshots. That will play a factor in AFRs as well.
