Injectors don't have anything to do wtih a boost controller. But.. there's really no use to having a boost controller when running 370cc injectors. Because, well.. a car is perfectly drivable at 260rwhp. It's when you have 50# or 72# injectors that will handle 350-450rwhp... you cannot drive on the street nicely at those levels. Even my 300hp is shredding 265/40/18 Goodyear Eagle F1 GS Fioro tires when rolling on the throttle in 2nd. So there, a boost controller allows you to run low wastegate pressure (7-10psi or so), and at the push of a button crank to 20psi for drag/street races.
And a turbo from a turbo'd factory car (like the t28 from an sr20det) runs at 7psi. The t3 from a z31 is also 7psi. Eclipses run 12-14psi, and the srt-4 runs ~14-16psi stock. Those are the pressures that the wastegate is set at, and you cannot go lower. So.. don't run an eclipse turbo on your 370cc injector KA. You will blow at ~300hp from lack of fuel. I wouldn't run more than 10psi on a 370cc setup. Because myself and some local KA-Ts run 280-300hp at that pressure. A smaller turbo will be 260-280hp.. which is right on the brink of danger.
