what will i be able to expletive with with the VAFC II....should i lower the vtec by 500 increments from 5200...or keep that stock...will i get more outta my IM I H E

 

do what? i dont understand what you are asking.

 

I think he wants to lower his Vtec setting 500 RPMs from the stock setting. He was IM/H/I/E

 

I am a SHE...and i need to tune my automatic prelude because my sister and i are racing next week she has a ITR....what i am asking babies is with the vafc 2 it allows to adjust vtec 500 rpm incriments...im not sure its right to go as low as 4700...because doesn't some lobe open at 4800...will the vafc 2 help get better performance out of my IM/H/I/E

 

the only way to know what is best for the car is to have a tuner do it on a dyno. just lowering the vtec ingagment would help by itself.
