Yea.. I had TF heads, SR and 219 cam on my 350 and it was ok. I was even using the stock chip with good results.

Your 22 #/hr injectors are fine,,, the ECM has sufficient range to correct for what you need while at closed loop mode. However, at WOT, you could be running slightly lean. Install an AFPR and dial in most suitable fuel pressure for your setup. AFPRs are often overlooked as a simple tuning tool.

As was said you may need a AFPR if a custom tune can't get enough fuel to the injectors or your duty cycle is to high.

You are better off running a slightly smaller injector at higher pressure for better fuel atomization.
Keep the 22lb injectors and experiment with 48-50lbs of fuel pressure.
Think: thumb and garden hose
