Empty bottle..low TQ?? After my nitrous install, we dynoed the car, and we didn't have a full bottle, so we used a near empty bottle, and I'm thinking my tq numbers are down quite a bit. This is a GTP St.2 heads, TR224 cam, and an NOS Wet plate kit, with an NOS progressive controller, and no bottle preasure.
542HP/542TQ
Here's the numbers:

WHY spray with an empty bottle? even still, the curve seems to follow the stock one except at the beginning of the nitrous hit, which isn't a surprise considering next to no bottle pressure.

Spray at 1000-1100psi.

It's actually not near as lean as it looks. The air fuel gets to around 12.5 in the mid rpm and then ramps up to about 13.1. We'll be putting some fuel in it once we get a full bottle.
