Almost stock power expectation

Hi. With the cobb green update, I'm aware that tuners are now unable to disable codes for emissions modification and overall check engine light, with that said I'm planning on getting a tune and of course before purchasing the tune itself I'm getting every part i have ready to be installed,

I currently have fuel pump internals upgrade and a ebay turbo inlet hose and short ram intake with 2.75 maf housing, ngk 6509, gapped to 0.027,

with just this mods with e30 fuel what could I be expecting? I also have a catless dp but I really don't want to install it as it will hit me with emissions, although my goal is only 300, you guys think that's possible with only those mods?

I'm trying to keep this car as close to stock as possible but also trying to hit 300,
I've been searching this forums and Google for answers but damn it's outdated and looking a some of the dates it makes me feel very old lol

 

I thought 330 was the ragged edge with a K04 on E-85, so 300 sounds plausible.

 

I think you'll be hard pressed to hit 300 without a dp those stock cats are very restrictive. It could be done but I wouldn't be surprised if you land somewhere between 270-300. That's assuming freektune or purple drank if you're tuned by drama tune it'd expect way less.

 

With emissions getting very strict, downpipes are less appealing now lol, and it's more surprising that it's very hard to get a downpipe now from ebay,, I just got lucky I have this downpipe as a spare,
