Stillen or gtm supercharger?

I'm glad to be wrong, I did not know that . Uprev will be the most cost effective option hands down .

Not many threads on their forum, but hopefully that will change with time.

can someone please explain why cracking the VVEL is important, and what does it do. Sorry for the noob question ive just been reading a lot of FI threads lately and VVEL is brought up in all of them.

I'll take a shot at this, and I might be off. Right now tuners aren't able to control the vvel, this you know. VVEL is simaliar to cam phasing. So currently tuners are adjusting timing, ignition, and fuel. Possibly others. But since they cant adjust the VVEL people are believeing were possibly getting blow through. So the way I see it is lets say me being FI i am running 7 psi but in all reality my car is only seeing 5 psi because the other 2 psi is just being blown through and out the valves. If they can control this they can leave the valves open or clased longer there can be more power to be made. Now there comes risk though. Alot of the tuners didnt want anything to do with this because they felt that the risk is way more then the benefit. risk being by controling the valves we can bend one and damage pistons, and they didn't want to be held liable for the damages. Another conpany just gave up on trying to crack it after alot of people bought there access port. Here recently sam anounced he is trying to crack. I don't know where he is at with it or if he already got control of it through the F-CON and is trying to make a smaller cheaper component that we can buy instead of a whole F-CON. Also as far as I knew SAM was the only one working on this. I remember uprev saying they weren't getting into this because the cost is greater then the benefit, but apperantly they changed there mind because they said they were working it. Most likely they are persueing it because sam showed there was a market for it and that it could be done. I don't know if I explained everything right but I am pretty sure I got the main parts off it. If I have anything wrong these guys will jump in and correct me

That was really helpful toner, thanks
