Default Back firing after nitrous pass help

So I just finished my nitrous kit install and am having a problem with it after it's done spraying. The car is a 2000 camaro with mods: yank 3600ss, 3.42 gears, headers, tsp duals, ls6 intake. The nitrous kit is a brand x bottle and solenoids with a dynotune 78mm plate. I am using an lnc2000 to pull 4* of timing for the 100 shot on a micro switch for wot and an msd window switch. The car feels good when it hits the window and sprays up until I let off. After I let off and am coasting and applying the brakes it back fires some. Currently running br7ef plugs and a 52n and 33f jet as per the dynotune recommendations. This is my first vehicle with nitrous and was hopeing someone would know a little of what's going on and if I should be worried about it.

Rich backfire.

Lower your fuel jet several sizes.

Learn how to read plugs and get a wideband as well.

That's what I thought it was. How many sizes do you recommend dropping it off as a good starting point? I'll try reading the plug just little paranoid living 45 min away from the strip and having to test ok back roads.

I believe that plate is a copy of the nos plate and there jetting seems fat as well. A 28 would seem to be a better starting point to me. Just for reference my buddy runs the nos plate on 63 36 which is probably a little fat as well, but nos recommends 63 38 which seems very fat.

I'll drop it down to a 30 and check the plugs this weekend and go from there. At first it freaked me out since it was my first time spraying.

Sounds like a rich condition. A fresh set of plugs will tell you alot also.
