Injectors? HE351 on l28et

Ok so not sure if this is exactly what we are talking about but I think it is 

I set required fuel to 300cc injectors. I've read these injectors flow 330 when clean and at 40.5 psi. That's all about where I'm at but I never cleaned them just ran them for years. 

Did some autotuning to adjust the cells down and drove a few miles. At 4-5k rpm with a fuel load of 160-180kpa two cells down from the top my pulse width goes over 25 might of even hit 30, and my duty cycle hits 120% 

I think injectors are the correct answer here right? 

I did a engine +map log but I'm not sure if that has the injector info on it or not. I didn't see a pulse width or duty cycle log?.

Welp. Got 550cc injectors installed and I'm pretty sure I spun a rod bearing trying to get this tune squared away. Not sure where all my oil went but I was a half inch below the dipstick. Would detonation cause this?. It doesn't seem like that's what was going on but I can't really explain it. How can one fuel cell be 10.5 afr and the next one goes full lean. Injectors made it better with some tuning but just as it started to smooth out on most spots. The engine made noise. I was an hour from home or more and I figured it was just the waste gate rattling on the inner fender.. fml. What can I do here once I rebuild it again to stop this from happening. I've heard knock sensors are like impossible to tune and to not waste my time.  Back a long time ago chicken man helped me out with my base tune and told me that I believe. I was still going on his tune with this turbo and never saw it over boost. Afr would just go out of range and the car would surge/buck the diff.
