Sounds like you need to get a tune from Justin at VMP Tuning. I had him dyno tune my car after doing the CMCVs and I didn't lose ANY power ANY where. I did gain more power mid-top. But it was a gain all across the power curve. I didn't lose any gas mileage either. Actually gained .5 mpg. I gained 12 rwhp from both the UDPs and CMCVs.

Yeah I noticed some high end power increase, but it hurts the low end torque a bit. Gears should help fix the low end torque loss.
Install is easy as well.

The loss in the low end torque is very minimal, but that's just the butt dyno. I don't have any numbers, and I don't really calculate my gas mileage.
Today, I uploaded my performance tune and it just JUMPS when you hit the gas, it's so sensitive, so I'm satisfied, and I can definitely feel the power gain from CMDP's. I had them for six months now and no problems.
Thanks for the suggestion though.

Glad to hear the number you saw with the UDP's and CMCV's. The butt dyno says I gained substantial power doing all three, but no dyno yet......
Oh, and as far as the factory crank bolt. I personally replaced it with a fresh one. For 6 bucks, why risk that stomach chruning feeling when you approach torque spec, and it let's go......especially on the crankshaft....

+1. I just had the UDP's, CMCV's, and Headers done last Tuesday. Using Justin's tune. Absolutely no loss of power anywhere.....

RE: Steeda Underive Pulleys
How old are you? I'm 19. I've had a 1990 BMW 525i, 2004 F150, 2006 F150, and now this 2008 Mustang. I have a full time job and go to school. I also have a 2007 Seadoo RXP. The payments are as much as a cheap car. I'm not bragging, just saying it's possible. So just because someone is young doesn't mean they can't afford things or their parents give them everything.

RE: Steeda Underive Pulleys
What the hell does age have anything to do with driving a Stang? Ya i'm 19, but I work fulltime to pay for the car. It's the only thing I really have to pay for because I go to community college. I work my a$$ off to pay for this car, but I think it's worth it.
Anyway,
Are you guys talking about the crankbolt? And I also heard that you don't need to rent any tools.
