Larger box size will help with efficiency, but you can't lower the tune if you want higher numbers. Tune to at least 40. I briefly read on the other forum that somebody suggested this and you said you'd have to plug the port to lower the tune for daily use, and that's fine. You'll have to do that. But you can't get a 145 with a lower tune.

your current port area is extremely too small!

There's already plenty of good advice over there. Do what NightShade said and try sub forward & a single 6" aero port to the driver's side. It's a proven design that works well. Also try just moving your current box around. Move it back to where it's almost touching the back of the car (with sub & ports still facing back) and see what happens. Then try turning it around and facing the sub & port forward with the box all the way up against the back of the car. Next turn it sideways and shove it into the far back passenger side corner firing towards the driver's said with the port against the back of the car. If you haven't tried this yet then get to work. Spl is all about finding what your vehicle likes and getting in that sweet spot.
