Sounds like it - mine feels that way sometime, but it's an old build with lots of miles on it, so I generally just chalk it up to that.
Yours..should not be feeling that way yet...
Boost is at the proper level? AFR?
The car did sit for like 10 months without being driven much. I started it up regularly, and drove around the parking lot, but it didn't get any real use.
Boost is hitting ~11/12 psi and 14 at shifts. I don't have an AFR gauge, and I kinda suspect AFR's part of the reason it feels sluggish. Honestly, I think the whole tune is just shoddy, so I wanna get it re-done by someone who knows what they're doing.
Couple of examples:
-> When I was driving it the other day, it just stalled when I came to a stop. An auto should never do that, obviously.
-> When turning on the A/C, it affects the RPMs much more than I'd anticipate. Sometimes getting close to stalling.
-> I think the boost gauge was wired into something wrong, because ever since it was installed, the dashboard can't dim with the knob. It'll only do full dim or full brightness. The auto light sensor acts strange too.
Wouldn't hurt to re-check compression too, I suppose. Haven't done that since before the SC build.
The pistons aren't much better but yes the rods are generally the weakest point in these engines. If you did pistons and rods then you should be good for quite a bit more power

And mp81 sounds like maybe it's time to freshen up that engine, maybe some pistons and rods so you can push more power as well
Then maybe I should go for full forged internals if I wanna turn the boost up much more.
The engine should really be fine, since it's still got less than 70k miles on it. Unless there's some issue I haven't been able to find.
