i wouldn't do more than a bar bud make sure you get the fuelling checked,me personally would get rid of your mines ecu and buy a emanage,dastek,pfc etc.as those mines,blitz access,etc are all prerogrammed for different specs, and you can't really do much with them granted you'll remove fuel/speed cut,but for the money people charge for them you could have got a emu and probably mapped for that money,regards to the injectors standard will be fine for a bar
