I have bought a VAFC for about 6 months now however have not had the chance to have someone put it in, now what I want to know is the people that actually used one is it better running with a VAFC then not running one at all; or running one without the proper tunning will make your car lose power? I have heard alot of bad things about the VAFC but I have no personal experience or anyone close to me using one so I need opinions. IF both cars for have a gsr swap (same setup) in them I always thought that the car having a VAFC and the proper tunning would be better (more horse and run better) then the one that doesn't have one; am I wrong?

 

spend a couple of hours @ dyno fine tuning it...
and I was pleased with the results...
I felt the difference after..

 

no 2 engines are a like, VAFC is okay, i would spring for crome pro, or something around that nature depending on your mods.. VAFC all it does is trick the map sensor so if u have an 0bd2b car it will learn around it and go back to stock settings. what obd is the car? and what mods do u have that warrent needing some sort of piggy back computer?

 

piggybacks FTL

 

Here are my mods; B16A block with tpye r pistons, gsr head with itr cams, dc header, skunk 2 intake manifold, p72 ecu. I know there are other better things like the honda data but want to know if I should at the very least go install and tune my car with a my VAFC since I already have it, will I see some increase in horse power?

 

so lemme ask you...why pay to get a shitty piggyback tune...only to go back all over again and get it tuned properly with a rom editor/burner...crome is free...crome pro is inexpensive...youll spend more getting it tuned twice than just doing it right the first time

 

My question is should I put in my VAFC since I already have it will my car be better then it is right now without it, I don't care about tunning it twice I want to try the different setups to see the difference cause I will sooner or later change some mods to the engine....

 

if you insist on wasting your money...yes you can tune it with the VAFC...will it make more gains over tuning it with a rom editor??? nowhere near it...
