I am just looking for a little guidance here. I have a customer that brought me a 427ci LS7 forged motor and also a A&A Ysi supercharger kit/ LS9 injectors modified for 80lb flow and a LS7 MAF. I have already installed the motor and cranked it up with its old stock tune without the supercharger. It ran fine and everything but it would not run with the LS7 maf plugged in; only with the original (as expected).
What I am trying to decide is whether or not I want to jump straight into just doing a hack job maf after it maxes out or should I just go straight 2 bar. If I use the MAF where and how do I start tuning it? (do I just plug it in and start autoMAF or is there something else that I need to do to make the LS7 card MAF work).
The customer also brought me a set of modified LS9 injectors that are supposed to flow around 80lb/hr. Are there any IFR tables for these injectors or some like them? Or do I just use the IFR spreadsheet and make and educated guess?
I am attaching a copy of the original tune file unmodified by me from the last tuner. I will appreciate any advice on these aspects and was also interested in if I did go SD for the customer if the STFTVEcalculated PID is a good way to go or if there is a new way better than AUTOVE or STFTVEcalculated?
