I have a civic vti eg (uk spec b16a2 160bhp) i have fitted a uprated clutch, a ITR box with LSD, full mongoose exhaust and decat, plugs, leads, and induction kit.
so my next step is a manifold (4-1) and a re-programmable ECU.

Which reprogrammable ECU is best? i know hondata are good, but which hondata one do i need? how much are they? are there any others to consider?

Also next stage for me after that is stage 2 cams, followers, valvesprings, camgears, and a intake manifold. My question is are the skunk 2/ITR intake manifolds really as good a power gain as quoted on sites and thought by ppl? (ive heard 15-20bhp) thanks, ste
