well with a VAFC I doubt he could make much more HP. As you said yourself its a VAFC, you only had 8 adjustment points to work with. The only thing he could do is possibly lean it out even further
I am sure the AFR could have been a bit cleaner if the adjustment points were adjusted to different RPM points...

with a TCT of 1 there is no way that dynapak reads lower than a dynojet.... but with your numbers i would hope so.

the A/F is a bit on the lean side. you peaked at 13.8... I wouldnt feel comfortable running that lean if you do alot of WOT runs


If i were you, I would try for a solid 13.3-13.5 from 5k on up to 9k, you can still gain power up top, you have it hitting 13.8 at the wrong point, you need to tune it some more, and you will get more power after peak power....

Yeah.. I assume the AFR reading is little rich since they were take from the tailpipe instead of directly after the header...

I can use some more tuning, but there is only so much you can do with a VAFC I..

At any rate, I have already added some fuel to increase reliability since this is my daily driver...
