Just got a set of these in with Mitsubishi adapters on them for DSMs, Evo 8 and Evo 9. 2200cc at a 43.5 base fuel pressure and they are capable of being run at extremely high fuel pressures, unlike most fuel injectors.
The 1000cc version of these injectors tune, idle, and respond like a factory stock injector. We have tuned a bunch of S2000s, Acura RSX's, and turbo B-Series cars on the 1000s and they usually run amazing. The 2200s should hopefully kill the 1600s out there in idle quality and drivability. The main problem with the 1600s is not that they are too big, it's that they are just a poor injector and do not have linear enough flow, a pulse width of 1.5ms can actually give less fuel than 1.25ms. That can cause problems and force you to have to run the car richer at idle and part throttle with the 1600s to get any drivability.
I am trying these tomorrow on an Evo 9 with an AEM EMS on it. Even with an aftermarket peak & hold injector driver box, the AEM EMS can't handle the 1600s very well, so this should be a good test.
