Dynoed my LT1. took my 1994 M6 to a dynojet dyno tonight. ran a peak of 234 hp at 5k, and 293.82 tq at 3.5k. it had two misses, one at 5.3, and again at 5.7. i can't get it to miss on the street, i think it is the longer time at high rpms required on the dyno (1st gear on the street goes by a lot faster than 3rd on the dyno). fuel pump or filter? the car is stock except for a cutout. i thought the tq was good, but i was expecting more hp out of an M6 with a cutout? i wasn't running quite right to, so that may be it.

With a manual why didn't it get dynoed in 4th gear?
Another 4-5% in the 1 to 1 gear ratio in tranny...
Looks like that might be spark scatter...Opti crap may be causing your troubles...I can't really make out your dyno sheet to see whats really going on...It may be fuel related but I doubt it...If you dyno with a wide band then you would have a better idea if it's fuel, spark (opti or plugs/plug wires).
General rule for a "STOCK" M6 in that year is 250-260 SAE corrected, on dynojet in 4th gear.

Probably a little more....
Yeah forgot they had speed limiter in verts....
So, numbers wise your ok....Except you need to find and fix that problem///
You could actually feel the drops on the dyno right?
At that power level you could rule of tire slippage as the problem..
