upgraded pump with stock injectors?

Hey guys, I'm looking for more fuel. It is a daily driver. I'm looking at getting a 33% with Industrial Injection CP3 pump. over pump with stock injectors. Right now running smarty touch. Here's a log i did the other night. Ironically saw this post and it got me thinking. Any thoughts?

I just had a similar question. What I've found is that an upgraded CP3 is not needed until you get OVER 30% over injectors. So I think a bigger pump is probably a waste for you if you are wanting to stay with your stock injectors. If you are planning on boosting power in the future with bigger injectors etc. I certainly don't think it will hurt anything to run as is though.

As mentioned above I can't see your log if you posted it, but if you're having issues with pressure, I'd think a stock CP3 would fix it with stock injectors.

My stock CP3 can't keep up with my 50 HP sticks WOT. So it seems that at least 50 HP injectors and bigger need a bigger CP3 to get the full potential out of the injectors.

Im sure someone might chime in and tell you to try the Arson kit, but I don't think they're made anymore. I'm going to give the II bag of parts a try on mine.

The 33% ii cp3 is just a stock pump with a bag of parts in it basically. The only real difference in flow is above 3000rpm. They’re a decent option if you’re already replacing the pump, but they won’t support a lot more than the stock pump.

Just a FYI I put the arson 3 kit on my truck years ago didnít notice a huge difference. It did help some but one thing I did noticed I got rail pop after installing it. Iíve learn to drive the truck in a way that it doesnít pop . I have 100 hp injectors and my cp3 pump had about 180k on it when I installed the arson kit, i can drive the truck with the smarty on level 9 and it pulls hard but Iím sure it pull harder and run better with a 10m pump and hp tuners. So a new 10m pump is on my wish list.

What is the reason for wanting more fuel on stock injectors? As other have said stock pump can handle a bit more than stock injectors unless there is something else going on (bad part or tuning)
