Anybody out there with "power pullys" on you E46 M3? I trust Turner Motorsport completely, but I'm very hesitant to do anything to harm my engine warranty.

How about the HP claims? If you've got 'em, do you really feel the extra grunt?

Thanks

I've got them but then again when I pulled out my car it also had a new exhaust and diff gear. They say it gives you around 5whp which others have backed up as well with dyno pulls. I'm going to dyno my car soon and will have some numbers. I never did a stock pull so I will not know exactly how much power I did make off of anything.
