06 m7 timing key?

[luv2sledmt]

i have a 06 m7 with thing can, slp intake and 2.5 degree timing key. it developed a low end studder when i put in the key. i called bikeman asked if a smaller key would get rid of the studder and the guy was real quick to blame the can but it was on long before the key and ran great with it. my question is would a 1.5 degree key get rid of the studder or should i just put the stock key back in. thanks for any advice

I'd take the key out go back to stock. I believe alot my bog was caused buy the 2.5* Spend the $ on clutching or something. IMO
