"A verified DATA Sheet"/ That's news to me.
I used the stock injectors and the tuner commented they had some head room for fuel based on the % of one time. Every tuner is different I guess.

The only issue and it had to to deal with was a leak on the exhaust system.
The Exhaust guy didn't have the band tight. The result was the flanges ended up not parallel.
When I mentioned it to the exhaust guy his comment was basically "live with it".
Beautiful welds and a very nice run. Will not be back to his shop.
The leak messes with the air fuel ratios even though the O2 sensor is several inches up stream from the leak.
Tuner knew what it was immediately just by looking at the data.
We were able to tighten up the, very loose, clamp during the tune but it isn't perfect.
Don't run an Electronic Fuel Injected motor with out some type of exhaust on it. It messes with the learned tune and the results are not pretty.
I just stuffed mufflers on the headers with some bailing wire. Worked, for me, till I could get it tuned and an exhaust system installed.
