My friend just got a V-AFC for his 97 lude. He has a AEM CAI, Mugen Header, APexi exhaust, Test pipe, AEM cam gears, Aem pulies, msd ignition and a 75 shot of zex. when he gets his V-AFC tuned will his stock computer correct his air to fuel ratio and everything??

 

huh? the vafc is to correct the fuel flow for the a/f correction .
tell him to tune it all motor , amybe richen it up just a tad since you cant adjust fuel jets with the zex kit becuase its dry.
