Default FUEL PUMP


Hi guys checking in from Missouri with a few questions.

First of all im wanting to maybe put in a higher performing fuel pump and/or coil packs but not sure what route to go for.

Also just any other upgrades i can do other than what mina has.

With the normally aspirated engine you have one fuel pump and the super charged engine has two so you already have a margin above what you need

The second pump doesn't come on in most cases until a certain RPM

The limiting factor on the fuel charge to the cylinders is the engine ECU that will regulate the fuel trim ( mixture ) to a target value of 0.0 so in the factory state it won't just dump in extra fuel with extra fuel pump capacity

Supercharger pulley diameter upgrade ?

I do have the xjr. So im fortunate to have the pulley option and have had been looking around and trying to do more research.

I am just trying to better my car and the reputation for them. I feel like they have great potential but no resources.

If anything i was not going to leave the ECM stock. I was either going to get a programmer or tune it by taking it to a shop.
