What if your happy with just a mere 10 - 15 more horses? Maybe I'm wrong, but maybe a cold air intake would give about 2 extra HP, and a programmable ECU with the right fuel maps another 3HP, so your about half way to 10 HP already, you just have to figure out how to get the rest. Possible platinum plugs with a mega-size coil pack to make sure your getting an explosive spark and an under-drive pully; and possibly higher flow injectors. Just kicking around the thoughts here.
