Re: 96-99 454 Vortec owners?
I completely yanked mine, stock 4L80E. Just zero out the tables for torque steps.

Look for all the torque reduction tables and just zero them, it will be gone.

I dug and dug around, and ultimately tossed in a set of LS6 injectors and confirmed it to be 24.87 @ 3 bar, same as the LT1. But what I found on the net was wrong, it showed 28.8 @ 3 bar, which was incorrect.

It is sure hard to fight internet folklore, once it gets spread hard to decipher. I just did a lot of comparison, look at stock calibrations (that proves a lot) and was able to find out what was right and what wasn't.

Note these values are the PCM values not the actual flow rate of the injector.
Stock L29 454: 22.3 lb/hr @ 4 bar (so 19.3 @ 3 bar)
Stock 98 A4 F-Body: 0-10 kPa 28.7 lb/hr, 90-100 kPa 31.4 lb/hr
Stock 01 LQ4 6.0L Truck: 25.2 lb/hr
Stock 03 8100 V8: 29.9 lb/hr
Stock 97 Regal GS L67: 38.4 lb/hr
Stock 2000 4.3L V6: 38.4 lb/hr
