Spoon does not suck. They are one of the top tuners in the world, along with Mugen. They think smarter instead of working harder. No wonder y they won the 25 hr race in a FIT. Modifying the stock intake could giv you some gains, but like every intake for fit its not gona be much. For real power, as much as i hate to say it, goin the FI route will prolly be your best bet. I dont think the fit was made to go fast in a straight line, but does do a dam good job around curves, where it belongs. Thats why to have some real fun in these cars you should definitly look into beefing up your suspension.
