TBSS Upgraded Injectors need help tuning

I have a 2006 Trailblazer SS E40 ecu, I will skip the reasoning for the upgraded injectors but went from the OEM ones to some FIC #60 ones I downloaded the EFI data for them and input the values that made sense to me. I need to figure out what else i need to log and change to dial it in a little better without a wideband gauge. Unless i need to put one on. Anyways after all the reading i've done still confused on what my first step to do is ect.. It's like the more i read the more i get confused. So far i adjusted the B1203 (Minimum Injector Pulse Width) {B1204} Small Pulse Adjust and the {B4001} Injector Flow Base with the FIC data I think that was correct. Wondering if my next step is to log something which im not sure what and then adjust {B1210} Injector Flow Correction Vacuum?

do you have a power adder? thats almost double the injector size over stock.

no not really just long tube headers and no cat exhaust, I went with the larger injectors to do some mods at a later date cam ect..... I put in the 445CC ones Sorry those are the #50 ones.

Post your tune and the FIC data.

You gotta update B1210 and B1204,
