Flat spot 5k after fitting db killers

Had to fit very short 48mm db killers to my termis on the S4 in Thailand to get them down to the 95db that local fuzz are targeting ,,

Bike has PC3 , termis ,, airbox mods and my special map Mark 4low and was running perfectly without the db killers ,,

with them its still silky smooth and fine up to 4500rpm then it hits a flat spot until 6000rpm
and then it runs fine up to redline

i can start off the line and blast through the flat spot with full throttle all the way to red line ,no problem , but in high gears at constant throttle say 4000rpm ,, opening throttle the flat spot is a hesitation blip ,,

so time to re- write my PC3 map was thinking just lean it out a tad between 4500k and 6000k so less fuel is flowing due to the db killers ,, and see if that fixes it as the map used to have quite a fuelling jump at that point ,, tonight I have written Map5low

will see tommorow if im successful or have to tweak it more ,,


at least the cops are off my back ha ha
