I just helped a friend install a vafc in his s2k and was looking for some advice as to how much fuel are we allowed to take off the top? we dont have a dyno or a wideband...but im thinking taking a little fuel on the Hi cam wouldnt be that bad.

we checked the plugs after 10k miles on his car..and they were white. Im not sure if this is the normal the s2k...but to me it was running way too lean from the factory. since then...weve put new bosch plugs in....

so far...all weve messed with is the xover point. but we havent messed with the correction values. they are all 0.

Low-Hi 6000
Hi-low 5800
