Yep made it to the track and got some runs in with and without the spacer. Bottom line? I'll post the best runs from each group and let you make your decision. Am I taking it off? No. Why? I can feel a noticeable torque increase and throttle responsiveness in the lower RPMs.
With Wedge - DA 706 - 60' 1.712 - 1/8 ET 7.327 - 1/8 MPH 97.82 - 1/4 ET 11.337 - 1/4 MPH 123.20
No Wedge - DA 832 - 60' 1.777 - 1/8 ET 7.382 - 1/8 MPH 97.99 - 1/4 ET 11.393 - 1/4 MPH 123.10

Congratulqtions,
I'll take those gains any day for $120 and a half hour of labor. Performance costs money and small changes add up and I will give you an example.I purchased a new 2012 Kawasaki ZX14R in January and delivered it to Brock Davidson Performance in Ohio for prototype development of an exhaust system and other bolt on performance enhancements. The goal was to see what we could accomplish with what we could bolt on and pour in a stock wheelbase 2012 Kawasaki ZX14R. The bike made a little over 190 RWHP bone stock with less than 50 miles. With no internal engine parts changes or machining (the valve cover has never been off the bike) other than shimming the clutch springs we came out the other end of the bolt on and tuning process with 225 RWHP.
This is a stock wheelbase bike with no wheely bars & using the OEM rear tire that ran a best time of 8.80 at 160.4 MPH in June at Indianapolis. With the exception of the exhaust system all the changes made were to optimize the efficiency of the basic design not alter it.
That's what the wedge does. It is a simple bolt on part that optimizes airflow enough to make a small difference.

So if you were to add the Power Wedge would it replace the 1" Rubber Plate TB Spacer or go in line with it?

Currently 11.0x's with a 1.57/1.58 60' in 1600' DA on a 1480' el track. At 1.00 on the launch I'm already at 4800 and never less for the duration, so mid-range increases are extremely short-lived and therefore of little concern.
Mods on 2.56 geared '08 are Vararam intake, ported TB & IM, LG Street catless headers, Z06 mufflers, 3600 Yank, Hoosier DR.

If I make the swap at the track between passes, will I need to tweak my tune too? If so, by how much fuel/spark and at what RPM range.

Your MAP pressure will rise by .10 Lbs and your MAF flow rate will rise by about 4-6% on that combination.
The ECM will be fine with some mileage on it. It does not like back to back pulls without some dial in time. You can and people do it all the time anyway, but you will gain more after some mileage is run on the car.

I have about 60 miles on mine now. I have a few high RPM runs but no full WOT hits yet. So far I'm not seeing any problems with it but without scanning, I really couldn't tell you if adjustments could/should be made to the tune.
I'd also love to say I noticed a power increase. But, like I posted earlier, I'm not going to feel 6+rwhp/tq on this motor. Throttle response wasn't noticeably better either but unless the tires are spinning at 1/16th throttle, who could tell? I'm not one of those placebo types I guess.
All-in-all, I'm content with it.

That's probably not going to happen fully at all. The ECMs are only capable of making very small adjustments within the basic parameters set out by OME/the manuf. Even just a very small air flow increase from a better air filter is often difficult for the care to adjust (to the best HP), as the OEM ECU is not setup to do that. It's ranges of adjustment, overall are so small that is why folks wanting the HP gains from bolt-on or others HP mods, need to tune to the mod... always.

Just wanted to share my thoughts on the LS-2 power wedge since I know many people were awaiting results. I was very skeptical, but after reading some posts by JonDaMan I gave in and ordered the wedge for $99. I figured if it didn't do anything, I'd just return it and get my full refund. So far, I only have about 10 miles since installing. But I did notice a crispier throttle response. It might be the placebo affect but I know my car pretty well and I definitely can tell that it did not make it worse. Like many others have said, even if it's an 8 hp increase, you are not going to feel a drastic change. But, I think it helped a little and hopefully after some more miles I will be able to tell more of a difference. I'll post results again after a few weeks of driving.
