Unfortunately the "lump" between throws is a characteristic of the Z's transmission. It isn't something I really notice during spirited driving but when bogging around town it bugs the hell out of me. OP, I hope they took out the shipping spacers out of the front springs for you and that "choking" feeling is partially due to the highly restrictive cats. Other then that, welcome to the forum and post pics.

Sucks about the lump.

What is this choking you're referring to? I've heard good things about the Berk Tech High Flow Cats. Youtube vids of the Berk Tech cats sound great, very throaty exhaust - I'm thinking about getting those and maybe and intake and then a tune and calling it done w/ power mods for awhile.

Unless someone has a simple bolt on suggestion? I don't like to do too much to my cars while they're under warranty.
