If you are going turbo go with the m8, a pump gas m8 will beat a slp piped m1000, If your down around 5000ft the don't beat them by a lot but the turbo just keeps pulling, race gas for some real fun. My 09 m1000 should be "rated" around 200hp and weighs as much as a stock 09 m8. I have a slp kit, bd box, bdx intake, bdx oil delete and a few other things the only diff I can tell between a m8 and m1000 is a loss in power. But, I'm a bigger guy, where are you located, if your close and seem competent I'll let you ride it, to compare. It is night and day between a 07 or 08 m1000. It all depends on rider stile, But one thing is for sure if your not a skilled tuner you don't want a m1000, sometimes theres no issues and sometimes it is a pain in the a$$. I am just getting mine to really open up and still think there is more to gain. Its the best boondocking sled I've ever road, I have not ridden a turbo because I can't afford one so I just stay away.
