I run my car on a [circuit] track a couple times a year and would like to get a little more of a push when hitting the straights versus higher output motors where the Si seems to lose its competitive edge.

I'd like to entertain the idea of a direct port setup with a 55 shot. It doesnt really need to hit until maybe late 2nd gear beginning of 3rd gear as I can't pull full throttle until the exit where I'm already getting ready to hit 3rd.

I just want to get some feedback on this.

This is strictly a DD and the last thing I want to do is change the exhaust so keeping this tolerable for a baby in the back seat is a must.

It's an '09 with about 26k and I've only ever run 93 octane in it.... It's my baby.
