I put one of the spacers in my truck and I really like the improvement

I've seen dyno results on other vehicles and they had ZERO improvement!

Mixed results.  ClubTitan has several users with these spacers and some claim mileage improvements while other so no.  Some claim a low end torque boost, others say no.  One guy posted some dyno charts and the results showed a high end loss (like 3 hp) with the spacer and you just can't dyno the low end to get provable results.  Some complain about the whistle and others say they can barely hear it.  I have a friend who has one on his Sierra and the whistle drives me insane when I'm in his truck, and I can even hear it when he is about 50 yards away.  Some have removed and resold their spacers because they did not get satisfactory results.

Some people have had to trim their CAIs when they install the space to maintain fan clearance, so there is one thing to watch out for in case you may not like the TBS.

Another note is that the consensus is to remove the half screen behind the TB when installing the TBS.
