A/F question after Apten ported blower...
Since I have a Predator, and will be bolting the (Apten Ported) blower back up tonight, I was wondering if anybody has any idea what percentage % increase in fuel I should add (BEFORE I AM ABLE TO MAKE IT TO THE DYNO). I am thinking between 5-10% range?

I don't know if this helps, but I dynoed my truck before and after the Apten. 15lbs of boost stock was running 11.9...the same pulley combo became 17-18 lbs with an A/F of 12.1...and my MAS started pegging 5 volts around 5000 RPM's if I remember right. I would suggest data logging the MAS readings while your dyno is being done to watch this. MAS hits 5 volts pretty darn quick after you start making 17lbs.

I would richen it a tad if people are seeing their AF ratios lean out one or two tenths. Anytime you increase your horsepower and lean yourself out, you want to make sure you're running safer than you were. That's just my opinion.
Also, do you have AF ratios for your current setup? You may not need to change anything at all if you're already running rich and have room in your tune.
