Thank you, that's very helpful. I'm pretty sure we didn't clock the bushings because up until now I didn't even know what it was. I think I'll go ahead and get the parts you've mentioned first and then do it all at once since it sounds like I'll need an alignment either way.
My GTPP 6spd is supercharged, and when cruising at highway speeds I notice that disengaging / re-engaging the throttle makes the rear end feel a little bit "bouncy" or "jiggly". I'm not sure how else to describe it. It also seems to squat quite a bit when under hard acceleration in earlier...

Tires were sprayed liberally with belt dressing by the dyno tech. I didn't know it was a thing, but he swore by it (and they sounded extremely sticky).
I don't know for sure on the timing - I think I saw it go up...
Sorry I should clarify. Bought stage 2 kit used (dual fans, 132mm TB) but without injectors. PBDyno sold me 56lbs. They said it would be enough with BAP and 91 octane / 3.75 pulley.
Dyno pull was to 7500rpm
I've been getting the kinks worked out in my tune with Palm Beach Dyno. The drivability is pretty good overall, so I thought it was time to strap it down and see what kind of power it is making. FWIW, where I'm at in Canada I guess we run on pretty mediocre 91 gas.
Here's the spec on my car...
