no matter WHAT injector you install, whether it's 1zz or 2AZ, make sure to let the stock ecu learn the duty cycle after install. you cannot do this sitting on a dyno. you'll need to let the car go through a few heat cycles with each injector installed before testing on a dyno.
also, it's important to note that a dyno pull isn't going to tell you anything about closed-loop behavior, which is much more important than open loop behavior. full throttle pulls will undoubtably be in open loop, and the stock ECU isn't going to be monitoring AFR's.. at low boost the 1ZZ injectors will most likely get you closer to 11:1 than the 2AZ injectors, but again, this has nothing to do with your original argument about tC injectors vs "missfire codes".
good luck, post your results. dyno sheets only tell us so much, street tuning with each injector size installed is far more valuable in the real world (street tuning while monitoring AFR's of course)
