I have a b18c and im pretty sure its a p72 ecu. I'm planning on upgrading IM, intake, exhaust, Headers, cams+gears, valvetrain, type r tranny, and possibly milling the head for higher compression. Would I be wasting my money getting hondata with just these mods or would just getting it chipped be fine. Also is there any gains from having a p28 vs p72? Would a vafc help on either application or pointless.

 

?

 

Well the P72 chip does have the secondary butterfly for the GSR intake manifold so that would kinda hurt you alittle so for that getting a chipped P28 would be good. As far as the VAFC unless you are gonna get it tuned by a pro. there is no point because all you will do is screw with it and make you car slower.
