Racetronics 42# scale? Anyone? Where to start? I need a ball park place to start. I added enough to the stock table to bring the first value up to 41.99. I think i have this messed up. Should I have multiplied it? Its ok cruising, but into it the a/f goes to like 9:1

Don't guess. You need to measure the fuel pressure at the rail with a mechanical fuel pressure gauge and use this calculator for the correct injector flow rate. Then you can copy and paste the values into the tuning software.

does he need to measure the fuel pressure with new injectors on or off?
