Decent mods... Not so decent hp increase

I figured I'd chime in. I have an '04 coupe 6mt with only 44k miles on it. Based on what most folks state as average ~228whp/~230ft lbs torque range for this car from the factory, I have installed a K&N Typhoon CAI, MD 5/16 Isothermal spacer, MD MREV2 lower collector, Berke HFCs, and Borla catback dual exhaust. Keep in mind, after a certain point of engine break-in, the higher the mileage the more incremental HP is lost due to internal engine wear.
Bolt-ons before tune = 263whp/243ft lbs torque
Bolt-ons after Osiris tune = 270whp/249ft lbs torque
Osirius tune alone yields ~7whp
Dynoed at UpRev using a Dynojet.
Off the top of my head, the only other things that I could possibly install without going FI, would be a larger throttle body and headers (which are a pita to install).

At this I don't plan to spend ANY money to make more power. These motors are relatively unresponsive to mods unless you go turbo/super.
I was used to SBC that would gain 20-30hp on headers and a cam would get you another 50 or more. This motor cost way too much to make decent power.
Handling/brake mods, that's a different story.

Stupid me bought the car thinking it was like any Mustang or Camaro and I could expect to upgrade intake, exhaust, cams and find an additional 50-75 horsepower. I was quickly disappointed, but I should have known better to begin with. Infiniti engineers spent their time in physics class studying. Ford and Chevy engineers from the late 90's spent their time in class making paper airplanes and lighting their farts on fire.
All the "low hanging fruit" has already been picked by Infiniti's engineers.

that dyno graph looks wierd like they were on and off the gas or something. should be a smoothish line not all over the place. stock afr's are around 11-11.5 under full load. alot of parts dont work that well on your car without a tune and you will have to do one to get the full gains out of them. i would try a different shop though.
