Car is e-tuned and runs great, but was pushing the limits of the stock injectors on my '04 WRX 4EAT. Upgraded the injectors to the dark blue 565CC ones. Adjusted the latency and scaling in the map and while I need to dial in the fueling, it's not too far off. The strange thing is that when I'm on part throttle and hold it right around 3K RPM, the car surges a bit and when logging I see it going in and out of CL/OL. I can reproduce the behavior easily and if I'm above 3K RPM it doesn't happen at all. No idea what would cause this. Any other tables I should look to modify as part of the injector upgrade? Any suggestions for troubleshooting? Thanks!!
