The mods I had done were. Kooks long tubes with matching catted h-pipe, under drive pullies, flowmasters, and a C-L intake with tuner.
I only had 87 octane in my car so all they did was load up the 87 tune once all the work was done. I dropped her off with exactly 304 miles on the odometer, After the lower springs were installed ( 1 inch front, 1.25 rear ) which by the way makes her look awesome ( pics will soon be up ) she was loaded up on a mustang dyno and 3 pulls were done after the tune was loaded.
The first pull netted 292.2 rwh and 304.1 tq
The second pull netted 294.6 rwh and 307.2 tq
The third pull netted 297.3 rwh and 310.5 tq

Each pull netted more hp which the tech told me was due to the fact that this motor is still new and tight. I will be back there in a week or 2 after I get about 1k on the odo and I wil make sure I have 93 octane in the tank.
after we talked and i was showed some info about other 05-07 cars they have tuned with similar mods they assured me I should be aROUND 310-315 rwh easily.
I only got on her hard once before I dropped her off and again after I picked her up and I can tell you she now pulls like a freight trane from 2-6 grand.
The smile on my face from the exhaust sound still hasn't faded it sounds so sweet with this combo and I will post a video soon.

Yes I am one happy camper

 

Nice numbers you should look up blewbyu. He has the same mods almost and his numbers are really fantastic. so yours should go up with break in.

 

Yeah, with those mods you will see your HP numbers go up significantly once your engine breaks in. Flewbyu made almost 340 RWHP and 362 RWTQ if I am correct with the same mods as you basically. 304 miles is not that much at all. I'd say dyno it again at around 1000 or 1500. And your #'s will be much better IMO.
