[sweld]

09 m8 slp y pipe and pipe, mbrp can, boysen rage cage and speedwerx air horn, it is running super rich from idle sputters until it clears up then runs really good no other problems in mid or high range, best as i can describe it if i slowly come up to a little hill climb or jump lets say then punch it, it sputters for a second till it burns up the excess fuel then takes off, checked all clutching componets everything is good, gonna change the plugs, what about the power valves? could that be it? i have 500km on these upgrades and has not dont this till now, any other suggestions? thanks shawn

Had the same problem on a 07 m8 with the SLP set up, installed a boodocker and took away some fuel below 3000rpm, worked great.
