I have read that the #7 cylinder runs leaner than the rest. Is this correct? Which cylinders run the leanest? I am switching to bigger injectors that came with a flow sheet so if I know the cylinders that run the leanest then I can install the ones that flow more in those cylinders.

I will be running 15+ lbs of boost so it might be more important than if I was running N/A. The injectors I am using are in this thread: https://www.performancetrucks.net/fo...=416134&page=2

 

Assuming that the injectors are in the following order:

8 - 7
6 - 5
4 - 3
2 - 1

I had the injectors that flowed the most put in the back and weened them out until it reached the front. I am not sure if the intake was causing the #7 cylinder to go lean or if the cooling causes that cylinder to fail more often. I figured that if the back cylinders were a little leaner than the extra fuel would help and if it was because they were running hotter than the extra fuel would help cool them.
