A scan would still be helpfull, but I dont believe your ve is correct. Your maf table is almost stock. Needs to be dialed in. If you dont have a wideband, buy one. Search for 69lt1bird, in his signiture you will find a tuning guide. DO NOT run the nitrous until you have this dialed in, it will make short work of your engine.
Also, you did not mention what injectors you have, not familiar with the data you have, make sure its right.
I have 20lb svo injectors...and yes i know about the nitrous...had a different engine and it was tuned for that...not i have a different one and trying to get it dialed in...I've got a wideband...innovate lm2
I am unfamiliar with 20lb svo, have never used them. However your injector data is most definately wrong. If they are in fact 20# I dont believe them to be big enough for your combo. I would suggest replacing them with something bigger and getting the correct data before you begin.
There are 39 # and 42# svo injectors, your data is incorrect for either. Start with that, read the tuning guide and understand it. Dial in your ve. When that is done do your maf. Pull at least 4 degrees of timing out of your table before you start. Change your pe to something like 1.245 for tuning purposes, you will need to lean it out after tables dialed in. Your current commanded 10.5 afr is way to rich.
