I just got it tuned tonight. 217.76 HP 150.63 TQ. The problem was that the original guys I went to never even touched the car, but instead printed out a dyno sheet from anothe s2k and put my name on it. Thank god I didn't give them any money. But with the new guys I went to I was able to gain 9 hp and 5.5 tq over my base. I'm very happy now. I do have my settings if anyone is interested. I didn't get a narrow throttle tune set up though, not that I really need it.

the ecu shouldnt be able to reset any settings because the VAFC takes the signal after it comes out of the ecu and modifies it..... at least thats how i understand it and from the wiring diagram on a VAFC it makes perfect sense.....

It's only tuned for full throttle. I didn't need to have any partial throttle settings since the only real time I would need the power is if I have the neccessity to accelerate faster than the person next to me 
I can really feel a big difference especially shifting into third. It takes off like a rocket. I'll try to post my sheets here in the next few days when I finally go back home. I'm getting out of the Marines on Friday, so I can go back home to TN and use my scanner.

High, im the current buy for an s2k. I hear u all are talking about vafc2, ive got one for my prelude. But i get alot of hating saying its a useless tool for tuning. Most pple say tune with hondata, chrome, neptune, p28, greddy ultimate and so forth. I get alot of hate on the prelude forums for simply have an SS prelude to start out with. But i see you guys dont mind vafc2. If i get an s2k, i will take off my vafc2 and put it on the s2k.

The VAFC is a pretty good mod for the money...I think the main reason people hate on the prelude forums is because the Prelude ECU looses the settings all together when tuning the VAFC..Or that's what I have heard anyways..When I had my VAFC 2 in my Si, it made some really good gains...It even kept all my settings, because I had to go back a couple times when I got head/ valve job done....
