gmpp touring exhaust
zzp s3 heat exchanger
60# injectors

I run a 2.5" downpipe on my car, and it is the optimal size for my setup (275whp on pump gas, 285whp on race gas).
ZZP, has that disclaimer so N/A 2.2L & 2.4L guys don't go install a 3" downpipe on their cars.
Auto will have a little lower power to the wheels than a manual.
OP, I don't think your numbers are bad at all. Don't get caught up on dyno numbers.
You can go to a different dyno, and end up with totally different results.

You can try to go with the 3 inch DP, but you shouuld be fine with the 2.5, so stop stressing the DP...
If you are trifecta tuned, have you sent vince any data logs?

but that disclaimer is still not clear to everyone.
The 3" is mentioned to be intended for blown cars, because a 3" downpipe on a N/A car is not neccessary. That's what that disclaimer is for. It's not telling you if you are supercharged you should by the 3" downpipe. It's letting N/A guys know they should buy the 2.5" downpipe.
but yes, both downpipes will work fine for blown cars.
