3" or larger DP needed?

[87BuickMan]

I still have the stock DP on my GN, and was wondering if it was realy worth the $$ to go to 3"? I have Ported stock heads, 009 injectors,AFPR, new stock turbo, .020 engine, just above stock cam, stock intake, DH & TB, D5 converter, bascily stock, just a few upgrades.

this is just my opinion but id leave the stock DP on there until you are ready to go with a bigger turbo

I was just wondering if a largerthan stock one would benefit me? I didn't realy word the title that well I guess.

I did not notice any HP gains with a bigger DP. I did notice the way the car ran when I eliminated the converter and went with a better exhaust system.
