Good question, ask FP.

He did the upgrade and even after retunes, he reported that he had a loss of power with the larger injectors. I was under the impression our injectors would do up to something like 300HP with no issues and to the best of my knowledge, no NA has anywhere near that, unless it is using spray...

Just offering what I know of the upgrade - if it does work and you can report back good news, I am all for it, but no one has shown dyno gains with the upgrade, and the ones who are still suggesting it have no proof of gains that I am aware of.
