okay, heres the dyno sheet.


and here are the wideband read outs from my LM-1. Unfortunatly, i cant get them to precicly coinside with the corasponding dyno run, and im not sure which run is for which dyno read out. however they are similar enough to get the idea, and to help me figure out my bouncy-bouncy boost issue at high boost.

wideband reading #1:

i think this was my first run at 9psi.

wideband reading #2:

this should be the run i did at 17.2 psi.

wideband reading #3:

this one should be after i dialed my boost controller in a bit better, at 16 psi, i think...!

okay, so what do you guys think?

Something's not quite right, is it me or does the torque curve vaguely like a sine wave? It just seems weird to me.

hummn..

next time make sure the idiots running the dyno use atleast 6 straps to hold it down to the rollers..

looks like your tires were sliding on the rollers..
