I just traded in my 13 ST for a SHO. I was tuned, catless down pipe, intercooler and cai upgrades and loved it.....until I found out what little hp I was getting after all of that money. I didn't feel like the money it would take to get a bigger turbo, meth and a few other things to get over 300 hp was worth my time or money so I got the SHO. I got a 14 and tuned it 2 days later and am VERY happy with how much more hp I got out of the tune. My kids appreciate the extra room in the back seat also.
