Default Distribution limits

At what point does the 99-07 truck intake begin to show signs of significantly uneven nitrous distrubution? Either via a plate setup or single fogger pre-tb. Or maybe one of each

My specific setup in the works is a sbe 5.3 with 4.8 flat tops. About 11:1. Custom nitrous grind around 226/236 114+3

Everybody knows a direct port will give better distrubution and allow you to balance the kit for each cylinder, but at what point is it actually necessary? 200?!300? 400?!?!

I am running a fast 78 with a single nozzle 200 shot and have great distribution. You'll find most people will say to stop at 200, some will say 250. I say keep turning it up until you find where the manifold starts causing you distribution issues.

If I can find an 82 and 88 jet before tomorrow I'll see how the fast 78 does with a single nx nozzle tomorrow.

I've sprayed 99 jet on a stock ls6 intake with a 78 nitrous outlet plate kit. #6 was my hottest cylinder and I always had to tune to that cylinder. Not sure if that helps but I don't have any experience with truck intakes.

Only hit it with the 78 jet as my local speed shop only stocked nos jets. It did pick up tremendously on that hit and distribution was great.
