Hi All

I got a my98 classic and have the following few mods

56 mm freeflow exhaust
k&n airfilter
unichip
intercooler water spray

running at 0.8 bar and producing 198kw engine output ...

I want to up this with a bigger exhaust but am worried about the fuel pump
is it a necessity to upgrade the fuel pump first to ensure that the duty cycle is well below capacity ??

looking at a 76 mm exhaust and maybe up the boost to 1 bar ???

thanks
