What's the meth mixture? I wonder if you have to much water not enough meth hurting power. I would try dyno runs on and off meth (obviously different tunes with each)
Also why are you running off the MAF instead of boost? Is your controller progressive injection? I had a devils own kit on a cobalt ss and it would start injecting at 7psi and go full squirt at 12psi until max 17psi. Reason I ask is if its dumping 100% at lower rpms it will cause the engine to bog.

using the MAF cause that's what they (snow performance) suggest for a whipple supercharger on a f-150
and it is progressive.. comes on around 4000rpm..
I think you need to get the truck dynoed, a non meth tune and a meth tune I'd be interested to see what happens when the meth kicks in. I wonder if it actually cools the IAT down so much (depending on where your sensor is) that the truck pulls timing thinking its to cold? I know mine doesnt advance until IAT is over 100.

update...
still waiting for VMP
tried to launch in 2wd..
NEVER going to happen with out sticky tires
either I got a terrible 60' or they just went up in smoke..
oh well.. it was humid like 60% and still was able to run a 14:33 @94mph
that's why I like the meth kit =)

What configuration was the EcoBoost? Do you go past 3rd into 4th in the ¼? I run through 3 gears (Manual Trans). I launch in 4Hi then shift into 2Hi after I get going.

I'm curious as to what the Meth is doing.
That was my thinking in an earlier post. I wonder if the timing needs to kick in at lower iat

ecoboost is one bad machine with a tune! I would rather put a blower on a 5.0 if I had the option. I had the 5.4 and had nothing but trouble with it, couldn't get a good tune to save my life. I had both a vortech and whipple S/C. I also put in a race built tranny, re-geared, e-fans etc etc and I was never satisfied with it's performance. You gotta pay to play.. good luck to your choice!

yes I did relocate the MAF..
Ah ok good lol. I would see What your iat temps are on the meth. I wonder if its cooling to much reducing timing. Justin is a good guy I would data long the quarter mile passes and see if he can give it more go.
