00 type r engine with injen intake, jdm 4-1 headers 2.5 collector with 2.5 test pipe, itr exhaust, msd ignition, the problem is that on half throttle it pulls pretty hard like normal, but on full throtle it lags really is it because of too much air i hear alot of air trying to come in but it don't makes power, do i need to tune it with something like a chrome ecu or should i just get a fuel pressure regulator with a vafc2

 

Yes, a OBD-1 ems (crome, hondata, neptune, etc) would definetly improve your engine response.

 

would a vafc2 do any good

 

not really unless ur really good at using it but its out dated... piggy back is the way to go for the money.

OP, your best option is going with a chipped P28 and a good tune.

side note: I always thought vafc was a piggyback.

 

my jdm itr motor also had that low end lag until i tuned my car then it ran better.

 

Get rid of the MSD and go back to stock, then tune.
