First-time tuner here, be gentle. :oops:

I upgraded the stock port injectors (228cc) to a Deatschwerks 450cc set, and I've been trying to tune them since (ECUtek). With a stock tune, it doesn't crank. As of right now, the engine idles somewhat normally. Not enough misfires to cause a DTC, but plenty enough to feel it. As soon as I tap the gas, it goes way lean (19+ AFR) and cuts out. Also, I upgraded the fuel pump, but based on what I found, tuning shouldn't be necessary for that. Please let me know if this is not the case.

For tuning, I followed the port injector tuning section in my manual and put in all of the manufacturer calibration data that came with the injectors. With just those changes, I am in my current predicament. I'll be uploading log data from my most recent attempts, and the ROM I've been editing.
