Well, Digital Tuning cannot upgrade my ECU. It's N340... they only accept N332 and N333 ECU's. Are there any other ECU upgrades that are available for my N340 ECU? If not what can I do to "beef up" my fuel system? I have a Walbro 255LPH fuel pump on the way and will be purchasing a full Racing Beat exhaust. Any advice on injectors? Will I need aftermarket injectors?

 

Depends on how much your boost goes up.

You CAN buy a SAFC and tune it yourself. That'll take care of mostly everything.

 

Hmm... alright. I did actually notice that Racing Beat sells a fuel cut controller.

 

The "bang for the buck" setup:
1) Bigger secondary injectors - usually 720's
2) Apexi S-AFC or equivalant piggyback fuel controller.
3) A rewired 255LPH fuel pump.
4) Gauges: boost, AFR.
5) A fuel cut defensor.
6) A boost controller.
7) Free flowing exhaust.
8) Free flowing intake.
9) A street port job at rebuild time.

And - a budget for replacing frequently worn out tires!
