and where the 'f' is it? the lpg workshop mechanic said he hooks the laptop up and checks all fuel trims as well as changing the filter. the filter needs changing every 20 thou i think, so do i need the laptop work done every time or can i just change the filter and maybe get the laptop s**t done every 40-60 thou or something.
