[QUOTE="Joeblue5.0, post: 16472499, member: 195473"] I have a 2013 Reg cab 5.0 F-150, pretty much full bolt on with JLT CAI, 85 mm t/b, Boss intake manifold, GT/Boss intake cams, Kooks L/T with their race catted mid pipes, side exit ford performance/Borla exhaust, 4.10 gears etc. etc. I have always run a 125 shot(NX Express wet kit) on e85 with no problems on stock fuel setup. I bumped up to 47 lb injectors and added a vmp boost a pump, and also requested an updated file for a 150 shot. The new tune seems a little more alive lower in the power band, but I've noticed that I went from seeing anywhere from 45-46+ lb/min maf flow to 36-38, also absolute load went from .90-1.02 to in the .72 range. The new file is setup a little leaner at .85 lambda, compared to .82. Now I'm no expert with the tuning, and can attach files if anyone cares to put in their .02, but I wasn't expecting these changes, and with it being a wet kit and the maf not seeing the nitrous, I'm really concerned with the maf flow #'s...??? I reached out to the tuner, and was kinda just told they tune the maf. Any input is appreciated. [/QUOTE]
