anyone done this mod to their bike any good points bad points, I work as a tig welder and will do this before I have the fueling set up on the dyno if it is worth it
 
a few guys did it on Af1 and had positive results i believe.

Think Sabre was eyeing up doing it to his steed as well
 
thats the one cheesy I have all that is needed apart from the get up of my arse and do it mode
 
when i spoke with mark when i was gonna do it the centre pipe adds midrange roughly 3-5 bhp and the rear link add is top end of about 1-2bhp
this should take out the flat spot aswell which would be seen on the dyno

the only reason i didn't get it done was i picked up a set of arrow race headers which has sim design
 
there does seem to be a bit of a dead area around 5-6500 rpm, my next question is I have a power comander the non usb one should I sell it on and get one of them garbo chips until I can get a pc3 with usb as the bike will def need set up for the pc not good on new tyres how much does the chip cost
 
the gabro chips are v.good from what i have read, and if you tell him the mods you already have he'll take that into account when he maps the chip i believe but you would still want a pcIII to fine tune the fueling
