    For all the high mileage guys

    I just dynoed my 99 Z28 M6 today and remember seeing alot of posts with people asking how the high mileage cars are holding up. So I figure I will post my numbers since my car is pretty much stock. It has 136K on it and when I got it the only mod is a SLP air lid. My clutch is worn so I think it cost me a couple but its still a good base line.

    RWHP: 288
    RWT : 308

    So there ya go. I did two pulls and on the 2nd pull it was up 6 RWHP but there was a big line so I didn't get to do another to see if it went up anymore.

    That's pretty good
    I dynoed mine 2 yrs ago on a Dynapack. At 109K miles and on the original clutch she made 300 RWHP and 322 RWTQ. Only mods were an SLP lid and a 3" Flowmaster SOTL Catback.

    im not sure what it would cost. ive just heard around here on the board that people have been saying a couple hundred is what to expect to pay. so i could be, and am more than likely wrong. but just going off what others have said.

    Youre probably thinking dynotunes those can run a couple hundred

    dynoruns are cheaper around 60-90 bucks.

    its typical that an older engine looses power due to all that compression leaking somewere.
