So it wont even run half decent without a custom tune? I figured I could atleast drive it until I could get it tuned. Is this common for a minor intake swap?

Stock injectors are like 28 pounds. Your PCM has no clue that you swapped the injectors, so you are basically drowning the engine. I wouldn't run it until you get a tune as you do not want to wash down a cylinder.

I didn't bead a tune one I swapped to a LS6 just had the egr and crap deleted but I used the same injectors. If you jumped from factory to 60lb injectors that will make a big difference. I know on my mustang when I swapped injectors I had to install a different sampleing tube in my MAF. I know on my friends TA when he swapped injectors they had to retune the car to work with the new ones since his factory injectory were maxed out.
