    he/she wants to knows power and with what mods you have

    i would say around or nearly 300bhp with eds3.5 map, consists of vxr injectors,turbo and afm, large smic,sports cat,pre cat replacement,dv,big jetex airfilter,xev inlet cam, uprated fuel pump,cat back exhaust,better tophat,coupe like not gsi but same engine

    judging by your signature, catback and other breathing mods, you'll be around 210-215 ish without a map, a map could take you to 230-240
