I say find a good tuner first, and then match a system to his talents. 
and if ANY tuner can't tune a VAFC safely than that is NOT a tuner, I mean all you need is a wideband and a dyno.
My dumbass was able to tune a VAFC and I have no tuning experience,
with that said, any good tuner is going to recommend you going with something other than a VAFC
LMFAO

Just curious but does your power curve drop off ant any point like most stock pre-04 dynoes? The flywheel doesn't really add hp, but it'll just make the power come earlier on. So it could be that you gained your power from your other mods. Also did you put in a clutch kit or anything with flywheel? I ask because when I had my toda(same weight as fidanza at 8lbs) my stock clutch was fried pretty soon considering if you do a lot of spiriting driving and quick shifts.

We initially got 7whp out of the VAFC II but this last dyno the a/f ratio was back to 12:1. I dont really understand why, if anything it should have run a little leaner than it was. Makes no sense to me but like I said I'm gonna get it re tuned to 13.2 range. Thanks for the info doods.
on the Widerange set to 99%, set your narrow to 0%

starts dropping around 8200/8300 rpm's or about 130mph in 5th gear. Are you guys using fourth or fifth gear? Since I'm using 5th my mods may be less likely to show up than in fourth. And I added an ACT clutch. Same combo I had in my last car and put 20k miles on it and took it out and it looked pretty darn good still. I like the ACT + Fidanza combo.
Your forcing the engine to work harder than it has to...thus putting less power to the ground...

Crower's stuff works great on everything else...just the s2k's don't respond well to cams.
