I have an 04 H2 and very rarely have seen 10mpg. About ready to install a magnuson supercharger in the next few weeks, so with your supercharger getting 14mpg, I would be a very happy camper. by the way, how is the whining sound on your whipple s/c? I wish the magnacharger would whine on idle but it only does so when you kick it in..
