whats up everybody. 05 636 muzzy full exhaust, kleen air mod, -1 +3, k&n air cleaner, power commander. I have recently started to tune my bike once again. trying map after map. same effect between 2-8k rpm under WOT its sluggish. then at about 9k it opens up real strong. been adding and pulling "points" to see if its running rich or lean. same ol thing. could it just be because of the full exhaust bigger piping there is not as much back pressure therefore losing bottom end? i can understand the lower power loss but damn..... when i first got it tuned they just pulled a map off powercommmander.com and it was real strong. battery got swapped and when i checked the mapping cause i felt the power loss it came back as stock mapping. so thats why i have started myself cant get ahold of that tuner anymore, i dont care to max out the hp or anything just would be nice to have a strong pull the whole way through. any help would be appreciated. thanks
