'07 RXP slowing down

[Kevster01]

Hi, My RXP has been giving me problems ever since I've bought it. I own 2 of them, one of which has no problems at all. At first, one of them ran about 2 mph slower than the other. Now it runs about 12 mph slower, and the rpm's are about 500 LOWER! I have taken it to the local dealership last year and they had no clue. They guessed it might be the computer? It has 32 hours on it. It loses power each time I take it out. Any suggestions about what it could be? Could be the supercharger but I heard it normaly goes out all at once. :banghead:

sounds to me like the supercharger is sliping. you need to pull the intake tube off and see if the impeller will turn.
