Default 09 Impreza 2.5i OS tuning help

Alright, so, I have an 09 Impreza hatch 2.5i, w/ 4EAT, with some UEL headers, modified mid pipe (cat removed) and a wrx style cat back exhaust, no rear 02, is there anyone who can help me get a good solid tune on this thing? I can get the base map and a logged map to whoever can help, and I'll have 100 bucks for that person, I know the gains won't be much, but I'm looking for a better curve, and better throttle response, and no CEL

Im adapting this for my 09 2.5i MT. I have UEL headers (high flow cat) and catback right now. My Exhaust retains all O2 sensors and cats however

Been looking around for all of those, most tuning databases ditched the NA powertrains awhile back. It'd be sick to get a 2008-2015 NA tune, but as far as COBB and all of the other big Subaru names go, its forced induction only. If you can throw one together do please share, just make sure for your particular car the lack of an 02 sensor doesn't make it run super rich
