They sent me the wrong shit lol . The replacement injectors they sent me are 450 cc I believe which with our crazy high fuel pressure works . The tune is even more important though because you can't just throw a big injector in you have to tune the duty cycle of the injector . Any way with the updated 525 tune and "correct " 525 injectors my problem went away . And FYI if I scan my ECU a brake booster error code still shows up lol . My point is it's NOT the damn brake booster .!
Okay, thanks for the info. I'll ask ESS if they think they standard pump can handle 450cc injectors (from memory you have upgraded your fuel pump?), and if so I'll get the injectors and flash it and see how it goes. Though if I miss my June 21st event it will be awhile before I get a chance to test it. Fingers crossed!
