I am going to avoid his problem before it happens. After i put on the Fuel Pump and 720 injectors the fuel system is going to run rich no? What fuel managment system should i go with to fix this?

While i got a new thread going i'll sk this too, when can i remove the air pump and do they make belts for car without the air pump only?

 

you have to NOT have cats to remove the air pump. they sell a dual belt pully and you use two alternator belts.

 

First of all what mods do you have? And you should find out if your car is running rich right now before the mods before you go adding more fuel and such. You have to ask your self if you really NEED more fuel at this stage. As far as adjusting fuel the best out there is the
Apexi S-AFC. I got one for $230 on ebay almost brand new. They go for $350 new so there not that cheap.

As far as the air pump, it depends what yourve done to your car so far. If your going with no emissions thats the best time to get rid of it cuz its basically doing nothing without the cats or the ACV.
