I have a 04. 5 600 48re and am looking to upgrade the valve body. I will eventually put a tuner back in, but for now it's stock. I drive 50% solo, and 50% towing about 12k. I've been looking at the DTT, BD, GOEREND, SUNCOAST, ATS, AND HTS. I've narrowed it down to the GOEREND or SUNCOAST based on my own research. Any thoughts?
