BTW, does the blue TBS match pretty good? It looks like it might. There is a new darker color blue now, but I think you got one of the previous more royal blue, which probably matches your theme better... Have you considered powder coating your plenum blue?

Without spacer
4500 160whp
5000 185whp
5500 208whp
6000 225whp
6500 228whp
7000 228whp
Average power: 206whp
With the spacer
4500 160whp
5000 185whp
5500 209whp
6000 225whp
6500 229whp
7000 232whp
Average power: 207whp

Ya, I see where you're going on this. It wasnt a big deal to dyno with & without spacer either, cuz I was at TS, & we were gonna tune the FX anyway. All that said, there is something to be said for the Butt-Dyno, & I'm telling you, you feel this spacer working. I'm not trying to sell this item, but those that have tried, like it.
I know my numbers overall do not seem fantastic, especially with the mods I have, But at least they are honest numbers, unlike alot of the BS found on the boards. My ride, although it does weigh in fairly high is pretty darn quick.

Thanks for the breakdown Dave.
But I have one question/comment. With gains as little as that, could that be acceptable variation in between pulls not just the spacer itself?
I definitely know it's doing something because my car is less hesitant (more responsive) at 2K rpms on the highway in 6th gear.
It's just with gains that are very minimal in that aspect, it's hard to say specifically that the spacer is what is causing the gain/loss.

It's quite simply actually... there is enough info out here to determine if it's right for you. If it's not then it's not. If you aren't sure that it is I wouldn't spend a dime if I were you (or anyone else who isn’t sure).

Its fine for people that haven’t even tried it to sit back and say it doesn’t work… some of the very same people say that about a bunch of mods – that happen to work very well on my car…
I just think it’s foolish for anyone to make decisions based on such nonsense… but quite honestly I couldn’t care less if no one else wants one. I’m way too busy to spend the amount of time I have to help get it to the people that wanted it.
It’s on over 55 cars – if it wasn’t enjoyed by the vast majority of those users you would be hearing all kinds of impressions that indicate this. The beta test period was a like it buy it, don’t like it return it offer… of over 20 people, only one was given back.
There’s really not much more to say guys. You can beat it to death… it is what it is. It’s on my car and my car has responded very well to it… as have many, many others.
For those of you that think I’m so damn creative that I am BSing you about all this… wow – you really have more time on your hands than me if you think something with this much history could have possibly been fabricated.
