Most of my pulls looked like the green lines, VERY wavey.

Could it be floating the valves? Crane dual springs setup by Lloyd with a comp 218/224 xfi cam and 8lbs of boost(although does it with 4lbs also)

Here is the graph vs engine speed, you can see the engine speed DROP at wot. :eek:

RPM VS TIME...

If BOTH were like the second one, I'd say someone left the factory 105mph govenor on it (non Z-rated tire cars had that), but the green one is like 118, so that doesn't make much sense.

That second one IS quite unique...

we def know it wasn't spinning on the dyno....usually when something falls off it seems to be fuel related but the car has plenty of fuel or should atleast
