Is it worth getting VPC on the stock twin's or should I just leave it for single or twin's upgrade?

I would get it if you plan on upgrading turbos in the future. I have it on my stock twins, and didn't notice really any power gains, but I haven't been to the dyno to find out for sure either. Just one less thing to buy when the single shows up on the front step ;)

Maury (Spool) just installed a VPS and GCC on his car.

He put it on the dyno to tune it and the car baselined 388 w/ VPC installed w/ zero adjustments.

With tuning of the VPC and GCC the car put down 428 and smoothly held til redline unlike most cars which power starts to drop about 5500rpm.

I think its worth it for 40rwhp, just no $$$ for it right now.

I would probably get a FMIC first if I were you though.

I have the s-afs and love the adjustability! Of course the GCC is the same brand as the VPC and may work a little better but who really knows....it is just modifying a voltage after all.

It gained 24rwhp on the dyno with it zeroed out and car still running super rich but it also held hp all the way to redline which was way better than before the VPC.
