I was responding more so to the first gen s/c question for ya...I have a 98 camry V6 automatic. Going back to the concern you have, unless your dealership has done a bunch of s/c installs, i would be putting together a quick punch list for the folks at TRDUSA. They would be able to alleviate any questions or concerns you have. Check out the 1/4 database at the top of the TN page in the red bar acrossed the page. There is a guy there who has been through a lot of upgrades on his toyota truck. Good luck and Have Fun~
