do many of you guys use the vafc? is it great? just some opinions and thoughts

 

I used it when I was boosted. Worked okay. I still have it even though the turbo is gone. It's basically sitting there looking pretty. But I'm allowed one "cool" thing on my car, IMO. But for mild tuning needs, it gets the job done fairly well. When I was boosted, I wish I had gone with another fuel setup instead of the VAFC, though. But when I got rid of the turbo and moved onto a S2S1 cam, I used the AFC (along with a S2 cam gear) to tune the engine, and it did its job.
