I heard its best to tune our VAFC2's for WOT only? Will my tuner know how to set it safely? Im going to Church, I heard he is one of the best here in so cal. And I may need to reset my ecu each week? Is this true? Do I really have to mess with my ecu weekly since I'll eventually be using a VAFC2? what do I do when it comes to smog check time? What gains could I get approx. by a pro tuner with my setup? (CAI/H/single exhaust)

 

bro my00 got the worst ecu's ..with the vafc you will gain alot and you will notice the difference..im not from the US but ive read alot about this church guy so i guess your pretty much tuned up and ready.

the vafc will just adjust your fuel so no need to do anything every week and so on. just plug and play

 

The VAFC will give you a smoother crossover is not anything else and give you good power gains mid range. as far as the resetting people have said the ecu will correct what the vafc has done. i never noticed it, but all it requires is you pulling the positive on the battery to reset the ECU. It is a solid easy mod and if you track you will like the lower vtec engagement
