i was only considering softronic, GIAC and FVD. they're all about the same price. i chose softronic because the owner has a relationship with PCA. besides, 18hp is just a number. it doesn't describe how different the car feels.
if i had wanted to put up big hp numbers i'd have bolted on an imagine auto supercharger or a turbowerx twin turbo kit. (turbowerx is right here in austin.) but i'm trying to keep the extended warranty in tact while increasing the fun factor. besides, spending your money on fast cars is a lot safer than spending it on fast women.
