All of the 87 or 90mm TBs will work with the X-Link, but the silver blade (pre 2007 LS7 and LS2 car) has a slightly different TP sensor range. The gold blade TBs typically will not work on cars originally equipped with the silver. I usually recommend the gold blade LS3/2007+ LS7 due to availability and pricing. The new style Nick Williams 102mm are currently having some issues.

 

 

I have email tq rush on this a couple month back they say all tb will work.

 

no they won't. currently dealing with a gold blade l92 tb on an 04. it pisses itself. the commanded pdl vs the tb tps and actual are all different and it's trying to shut the truck down.
