On VFAQ, it says a "210cc injector upgrade, a 4g67 ECU upgrade and a 4g67 MAF(? Mass airflow meter?) upgrade will give an overall increase in power"

True? How hard to do? Need a bigger/better fuel management system?

Hit me back 8)

you mean 4g37, not 67.

talk to Tim from ottowa, a.k.a. flying eagle
he has done this recently and documented all of his trials and tribulations.

I'm running everything except the ecu. The throttlebody with porting gains you the biggest benefit. The MAS has the other bypass hole opened so you get better airflow through the intake system. With the addition of more unmetered air, you have a serious lean issue. Thats where the 210cc injectors come in! :D More unmetered air, more fuel. I would say that it helps the top end breath better. Especially if youve done some porting and exhaust/intake mods. Without the proper ecu though, i am running a little lean at idle and experience surging on start up. I assume the surging is due to the 4g15 ecu telling the 4g37 throttlebody to open X amount when in fact it is too much. Then it has to close down some. Repeat till warm. I would think the 4g37 ecu idle characteristics would be much smoother.
