Need help immediately.....for those guys who tuned their s2k with VAFC, do u guy install other components?such as Injector set, throttle body, etc.....

 

no. its not necessary. sure some have installed other mods with a VAFC, but for the most part you just need to spend some time on a dyno tuning the VAFC.

 

...and if you install other engine mods, you will need to re-dyno to achieve maximum gains.

Most people add the V-AFC *after* other mods, though it's not necessary to wait to buy, and furthermore, stock cars with the AFC STILL show a power increase with proper tuning.
