Well we know they didnt use a "blackbox" PCM to rev that high with the L31.
3" stroke ehh, to bad we couldnt get the data for a 94-96 L99 4.3 GEN 2 engine as it uses the 3" stroke crank.

Have a better plan to investigate. Someone find me a HP Tuners .bin file for the same year 4.8 and 5.3 trucks and I will have a peak. Those two engines are identical minus the crankshaft and rods.
