I was going to suggest a tune as well. I’ve heard good things about Black Bear, but I’m still a little stingy and haven’t coughed up the $500 for it.
Someone just shed light on a Dual Throttle Body intake manifold. Darn thing is about $1500 (not to mention the extra TB, etc).
I like the sound of the cold air intake, but I’m not sure if it helps over a quality, dry, high flow filter? Others will chime in to this.
How about a shorter final drive ratio for some better “get up and go?”
I’m enjoying the Borla XR1 muffler. At WOT it will increase your exhaust velocity (even if you don’t have a muffler).
If you haven’t changed your spark plugs in awhile, that’ll help.
