i need a air fuel controller asap..... which one is better? i can tell the vafc is more popular out of the 2 but which is best bang for the buck....i need sum serious air fuel tuning so wat do u guys think? and is it hard 2 play with them? or once u tune it u cant touch it?

 

I had the vafc before.. hard to tune with that.. so I got a fields.. its much easier for me.. street tuning..

 

go with the vafc...just like evrything else it is complicated at first...and if u have a cool tuner im sure he will let you watch while he is tuning and maybe you can pick up a few things

 

I would not buy a fields or vafc unless I had to.
Look into a chipped obd1 ecu solution running crome, ubderdata, hondata, neptune etc.
