Hey guys, Just picked up an 06 MS6 from Morrie's Hyundai and I wasn't able to figure out pre-purchase that it needed the VVT redone...sooo...I've got a local shop that I trust doing the repair work for me. I was wondering if anyone has any opinions on using something like the Darrell Cox Racing VVT or some other aftermarket VVT versus the OEM unit? Is it worth it or would I be better served getting the upgraded unit?
