well after thinking about it for a couple days, i decided to order the new apexi s-afc 2 that came out, the one with the dial, not buttons. it said to have 12 point adjustable fuel curve, adjustable rpm in increments of 200 and a bunch of new stuff. anyway, just wanted the opinions of any safc owners out there. judging from the old safc, does this sound any better? or probably won’t be any different? also how hard is the install? i mean i can have knowledge of installing headunits, tv tuners and such, if its anything like that. is tuning it difficult? any input is appreciated, Thanks.
