I do not know for sure, but I would think that you could tell with a scan tool by monitoring pulse widths versus a truck with stock injectors. Because of the bigger holes in the 45% injectors, they need to be open for less time to inject the same amount of fuel. So if you can get fuel rates mm3 and pulse widths from a stocker, should help you out.
Also... if it has a stock turbo and a PPE boost valve, it is highly unlikely that it has 45% over injectors without smoking like a freight train. Well... it is possible, but the power numbers wouldn't be there and would be no need for it. Driveability would likely noticeably suffer as well, especially given the large tires. Other will hopefully chime in, I'm not experienced enough to be able to say what I said was 100% correct

Oh sorry, I failed to realize the year and as such was not the truck in your signature
 One thing you can try, is calling Daniville, give him the kids name and ask if he purchased that pump from him. Same thing with the injectors, try and call. They might say they won't tell you, but worth a shot. Too bad so many people don't keep their receipts.

The best way would be to put tuning back to stock and do a dyno test. It should also smoke pretty good on a quick launch. I find that quite often what is claimed to be installed for injectors often is not.

Look for a lift pump. I doubt even a modded cp3 could hold 45% without one.
