Since you are going to be running boost, I would go with the flowmatched and wiring kit. You don't want injectors they might have low flow numbers which could result in a burnt piston, or even have you chasing a rich/lean condition. So just for the saftey factor the few extra dollars is well spent. And yes, the wiing kit is plug and play, or going into the stock connector near the tank then you run the wire ti the alternator. it's a fairly easy install ( after you get the tank out!)
Question: How much boost/HP and you shooting for? I'm running the same pump/injectors and at 480HP am getting close to the limits. Next round of upgrades will require me to move up to a secondary pump and larger injectors.

Sorry, let me rephrase. I'm 480 RWHP and close to maxing out on the injectors. With boost you want to make sure you have plenty of fuel and you want to keep the duty cycles no more then 85-90%. So if you're planning on going over 550HP then I would go with bigger injectors, and you may need to plan on a booster pump.

It's true. It'd be a good investment to bump up to some 60lb/hr injectors if you are really wanting to push more boost, along with a secondary pump to be on the safe side. You do NOT want to lean your car out I'd say 12:1 is about the most lean I'd go.
