Ok so i wanna up the boost on my 87 tii and I have racing beat catback and intake and my car has run abit rich since I got a new engine installed so the intake helped even it out. but I'd like to upgrade the fuel system and i wanted to know what the best route would be without the use of a stand alone fuel management system... I realize that without this I lack the ability to tune the amount of fuel I mix with my air.

I was thinking I'd upgrade to a walbro pump and exchange the 550 secondaries for a pair of 680s. would this present any problems?

I also have an manual boost controller that is of no use to my right now since I have no fcd... but I figured I would not exceed stock boost limitations until I've made sure that I have the proper amount of fuel.

feed back would be apreciated. thanks..

A'PEXi S-AFC would help you control those larger fuel injectors.

without some sort of a controller (as ted suggested) your upgraded injectors would actually make less power than what you have now.

 

Would a HKS FCON system be ok for controlling bigger injectors?

Yes.

 

Not really
