My ALKYCONTROL tunning story.......
Well, when I first bought my STS kit I also installed an ALKYCONTROL meth set-up as well as a few other things. The pump for the alky kit started to leak after a month or so, I didn't really worry about it that much (put it on the "to-do list") Fast forward the end of the 5.3l I figured while the engine is out I'd seal up the leak, well turns out the housing is cracked. I tried to repair it being the tightwad that I am but it still leaked. No worries, I get meth cheap I thought.
I'm not the greatest tuner in the world, but I had such a hard time with my stupid truck. One day it was rich as hell. I'd lean it out, the next it was super lean. For the life of me I could not figure out why the hell the truck would change so much. The I tried to account for ambient temp changes. I also hated the fact that my truck would only handle about 10 deg adv. and I'd still get kr. from time to time. I've tuned quite a few other trucks (a few on this board) as well as a Radix equipped SSS. I did his tune in a matter of a few hours.
Well with my latest set of upgrades. The 05 front clip, 34" rad, 05 e-fans, removed MAF (tuning CLSD), relocation of the Intake sensor <--- That is the important one. I begain to retune. As I was looking at a few of my logs at WOT I realized my IAT temp was going from 70 deg down to 45 deg, I was thinking damn that methanol works good. Then it hit me I started check other logs.... sure enough. The logs I was way lean my IAT was climbing instead of falling like it should. When I was WAY rich the IAT was falling.
So I checked out the ALKYCONTROL pump. I hit the over ride button and could hear the pump work, I pulled the delivery side hose off and hit it again, NOTHING. DAMN.
E-mailed Julio, He said he could have taking care of me if I would have talked to him when it first started leaking (rather than me ripping the pump apart). I ordered a new pump. (At a killer deal) and installed it today.
I've already ran 12 deg advance and I'm now going to try 14*.
My IAT at WOT, they are at 45-50* EVERY time.
Julio also hooked me up with a new pressure module and LED. I can't say enough about the great service I have got from ALKYCONTROL. I just wished I'd figured this out a year ago. lol

I just did a bit more tunning and logging. I think there is still some more timming left, I'm at 14* at WOT now.
I had Two people in the truck when I did a 4 wheel drive launch and ran it up to 80 mph. comparing that log to my log of the 13.1 run I'm .157 thousans slower, but I had at least 400 pounds more in the truck.
I'm thinking 12's this next friday night might be posable.......

It is a great kit and great support. I have run into a tuning issue that I haven't found a work around for yet. Wonder if you will/have seen the same. Might be different with a turbo setup.
Spraying 100% meth, AFR went way rich at WOT obviously. With tuning I pulled fuel to get to 11.5 - 11.8 through 1st and 2nd gear. Problem is when I hit 3rd AFR then drops to 10.5. I can't tune it out. Anything I do to lean out third also leans out 1st and 2nd gear. Truck falls off a bit at the track when I hit 3rd. I do have some room to up my shift points, a 6500 rpm shift will carry me further through the 1/4 before hitting 3rd and might gain me a bit?

I am also looking for a fix to this

My problem was some times the pump would work some times it wouldn't. You could imagine how hard that is to tune lol.
