Sideways, from now on can you please clarify in each time you post advance and retard specifications that you list them with the word advance and retard. When you say +2,-1 or -1,+2 nobody knows which one your referring to as the intake or the exhaust. (or at least I dont)Thank you 
Im sorry to see you lost power with the keys. I really should do another dyno with my car, I just never got around to it, like many other people 
Did you do tuning changes when you install the keys, or did you tune the car without the keys, dyno it, then install the keys and dyno it?

The last time I did an install I needed magnification to see the keys adequately.
That is when I realized the degree number imprint is on the left with advance and on the right with retard.
Just retarding the intake cam a degree or two will make a huge difference so these results do appears suspect.

I had PMs with Sideways a long time ago when I bought the keys. Here is what he said about advance and retarding the cams.
"From the front of the engine, both cams rotate to the left, counter clock wise. To advance you off set the cam to the left.
I retarded the intake and advanced the exhaust."
The more I read this, the more I think the picture I made that is posted above is incorrect. Sideways, even though I think you have seen this picture and we have discussed it, please confirm it is correct for everyone. This is the way I have my cam keys installed

See it counter clockwise. In the Pic the exhaust key is offset to the right retarding the valve opening -2 and the intake key is offset to the left by 1 so basically its opening 1 degree faster = advanced.

Both cams turn left (counterclockwise.)

lets say you put the keys in reverse how much is it going to cost to reinstall them and get it dynoed?im in for pitching in money to get this back to the dyno.im glad it lost that much power if the keys are in backwards,should mean correctly installed should give at least 5%
I have wasted $250+ on this so far, but if enough people are willing to pitch in, I will gladly drive there again next weekend or even during the weekdays (I have half days for the holiday season), put the keys in the other way, and run some more dynos and give you guys a detailed post like before!
However, before we do so, I would appreciate it if sideways can possibly provide a drawing of how it SHOULD be installed, so we can compare them with the picture I have posted and see if we did indeed install them backwards. Like RAIN H8R said, I thought sideways had seen this picture and thought everything was good to go. Maybe there has been a miscommunication somewhere.

EDIT: So if every single person who posted on this page (page 4 only) pitched in about $20 each, it would be $140!
If we can get anything close to that, I can pitch in the rest and do the test! It will be another risk for me since there MIGHT be a chance I may have to pay more to remove them.
