Default Smartest throttle body option.

I have a 2001 C5 that I'm transplanting an LS3 into.

Slowly but surely my parts are showing up, and it's getting closer and closer to the big day. I'm still on the fence though about what to do for a throttle body.
My donor LS3 has the gold blade throttle body on it. Most people have said to ditch it and get an LS2 throttle body because the gold blade style will most likely cause issues with REP and CEL. Having said that, there are several instances of guys getting them to work either by wiring mods or tuning. I've also seen another product that appears to make the gold blade plug and play in an LS1 car.

Here's my options as I see it right now, guys help me figure out what to do please!

1. $50 for an adapter harness and hope I can use the gold blade via tuning or wiring. = $50 + time messing around.
2. $50 for an adapter harness + $400 for an LS2 throttle body. = $450 and guaranteed to work.
3. $250 for this "X-Link" harness adapter. = $250 (supposedly plug and play. Has anyone used this? http://www.torquerush.com/x-link.html )
4. Are there any aftermarket TBs out there that are wired for an LS1 but have a 90mm bore?
5. Something else I haven't thought of?

Obviously, I can just get the regular adapter harness for $50, then splurge the extra $400 for an LS2 TB if the gold blade one doesn't work out... BUT if something like that X-Link works, then I can just grab that right off the bat and I'm only in it for $250.

Hmmmm.... help me out fellas.

Tuning. It WILL work in your C5. I've done these swaps, so I know it personally.

Guys at ECS figured it out years ago.

You can do it with either HPTuners or EFILive.

Good to know! So it can be done with just the basic harness adapter, or do you need the X-Link one?

Do you have a tune, that I could plug-in for mine?
