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😂😂

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.

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.

You don't have a wideband?? Get one ASAP. Could be a similar issue mine had where it simply wouldn't go into PE unless you punched it hard. If you rolled into it, it stayed at ~stoich.

AFR = Air Fuel Ratio
Wideband = A sensor (O2)/gauge that reads the AFR - far more detailed than a narrowband which also reads AFR but cannot be relied on for tuning.

Yeah, it's an evaluation car from work, so you can either get it Mon-Fri or Fri-Mon. I pick Mon-Fri since I generally don't drive anywhere on the weekend.

Free hosters will be restricted to 25MB of hosting bandwidth per month. YOUR CURRENT USAGE IS OVER 500MB PER MONTH SO THIS NEW LIMITATION WILL AFFECT YOU.

What Happens If I Go Over My Bandwidth Allowance?
Free hosters, like you, who use more than 25MB of bandwidth will have all of their hosted photos watermarked and blurred.
Photobucket, back at it again!

Keep in mind, I don't know the last time I hosted a picture on Photobucket - those are likely all very, very old pictures - and I'm still twenty times over the limit.

Feels appropriate for an old meme... Scumbag Photobucket

Time to download everything and hope that Imgur doesn't start to impose limits!
