ok im planning on staying NA. i have a 93 si with a 94 b18c1 in it. mods are- aem cai/ skunk 2 intake/ 4-1 header/ test pipe/ 2.25 exhaust/ UR crank pulley, no a/c or p/s/ UR cam gears set at zero/ act prolite flywheel/ act hdss/ phantom grip/ and a p28 chipped by jhp.com with the ffs1 race program.

i have a 255 fuel pump ill be installing soon with a fuel pressure reg. i was considering going with a vafc but am wondering if it would be better to just get a hondata.

i will be tuning it on a dyno as soon as i can. how does tuning work with the hondata and would i really see any better results with it over the vafc if im staying NA. i will be building the motor eventually but not till it needs it.

thanks in advance for any help
