He's using a rpm switch from summit to activate the VI. The SAFC allows him to tune his car on the dyno, not sure what the VAFC does.

thanks dave. I would have bought the VAFC, but i already had the summit switch hooked up and everything. the VAFC is everything the SAFC is, only you can control the VI with it as well. It was an extra 20 bucks that i didnt need to spend, so I just bought the SAFC.

That's a good time for the crappy weather!!

I got 15.3@91 without the VI and my 17's w/ a 2.4' 60, im HOPING for 14's just as you are..

the 2.4 60' is CRAPPY so I hope to lower that, 2.2 or 2.3 :\

also could you send me your runfile

Im hoping to ****** a low 2.2 60'. Hopefully I can pull a 14.8 ish time. I'll go to the track again when its cooler. I just went the other day because all my buddies were going, so I figured why not. The trap speed of 93 is what has me aiming at the 14.8 mark.

What did you run before teh VI?

15.2 at 91 mph. with a 2.2 60 foot time
