Can anyone pose up your tune with the correct IFR table for 42# injectors in a 2000 Ls1? Do I have to change anything else besides the IFR table to properly skew the injectors? Thanks.

What brand of injectors?
Okay ill give you guys a lot of specifics and hopefully can give me some insight on making a good base tune. It should be ready to start for the first time this weekend.
Cam specs (234/242) duration .575/.595 lift with 112 lobe separation
3.70 Gear ratio
Walbro 255 fuel pump with dual feed 8an rails
Stock LS1 MAF
Polished heads and intake 1.96" intake valves and 1.64" exhaust valves
10.4-1 compression
EV1 Injectors flowing about 42# at 55 psi fuel pressure
Supercharger running 6-9 PSI of boost
I was told to start with a stock 2000 LS1 file that I picked up from the repository. Help me make a base tune so she will at least idle this weekend LOL

Any help with creating a good base tune would be appreciated. Thanks.
I am seeing that part number listed at 36lb
I found this info

Yeah those are not 42lb injectors. They are 34.54lb @ 3bar and flow roughly 39.88lb @ 4bar.

Great find! So you guys have any tips where I should start with to get this car dialed in? Should I start with a VE tune then move to MAF? On a setup like mine whats the ideal Idle/Cruise/WOT AFR?
Another thing im not really sure on is how to get change my commanded AFR? I know you go in Power Enrichment table but i don't know what 1.250 is as far as commanded AFR. Is there a formula?

PE is stoich/PE=commanded AFR. Using pump gas 93 octane, it would be 14.68/1.25=11.744
