I can pass you my Hpt files so you can see and play with some table numbers. I'm still learning so I had CSP Perf do a dyno and drivability tune.

The issue comes with the new MAF volume per everyone I spoke to.

I have snow on the ground so I cant get it out yet to drive the 102 and ported even on the current tune. So far idle and off idle seem ok. It was a touch fat before any way so it shouldn't need to much adjustments and I was only at 80-83% percent duty cycle on the injectors.

Cool, thanks. I'd be interested to see if your VVE is tuned. I'd imagine it might be easier to get the driveability to be great with the VVE in the background in addition to the MAF, as opposed to dealing with basically just the MAF input at the now much slower air velocities. But, I know most shops do MAF only for quick turn given their volumes.

It actually idled pretty good and had decent drivability with the prior scalar, I went to 7149 after a few searches and the idle is very solid. I havent put any drive time with new scalar since we just got some snow and I finally got my chiller parts.

Scaler @ 6800 for me (per Dave). ABADZL1 and I also accounted for the volume increase of the blower (Jokerz port snout/blower).

Running meth, E85, 5" CAI, and 102 NW... 1050x ids...

Good info. I was leaning toward 6800 b/c Dave's the man. Since Mark also seems to be the man from what I can tell, I'll be going with 6800 when I get there.

Ill try 6800 also, what exactly am I looking for in the difference?

Off idle?, Mid? Idle quality?

The good thing is now that I have HPTuners I can buy Dave Steck's Aux pump kit and program the FPCM.

Although I noticed that CSP and some others are using a manual Hobbs switch for activation. Thoughts?

I would use the fpcm, personally. Less stuff to go wrong and easier, in my opinion. I haven't done either though, so take that with a grain of salt.
