  1. edge evo race nooo power

    07.5-10 LMM Performance Parts Discussion
    i just installed edge evo race into my 08 LMM and i heard nothing but good things about the tunes but be honest im not impressed at all i hardly feel a power difference i feel alittle but not worth bragging about. i have tried level 3,4,5. i have a 4'' turbo back exhaust, but thats it for mods...
