yo! i got a vtec lagging problem on my b18c.. i got skunk2 cam stage 1, skunk2 intake manifold,..b16 tranny, and a pr3 chip mugen ecu.. with all of that.. it still lag.. it pull from the low rpm then hit vtec at 5300 rpm, it pulls, but not full potenial...it swap into my 4 door da.. is it the weight problem?? or something else?? Can someone help??

Or maybe..is it becuz..it obd-0...should i change to obd-1?????

 

its because of that ''mugen'' chip.

get something programmable, have it tuned, and you wont have that problem.

 

Well would it be better just to got obd1 with the p72 ecu???

 

go obd1 with the ecu of your choice, a quality ems, and tune it.
