Hi fellow audi owners. As i am looking at playing arount with the engine on my A3 1.8TQ i thought it would maybe be a good idea to put a boost guage in it as they come in handy for fault finding and know how its going. also i thought is it worth putting anything else in there? oil temp or pressure? to be honest i didnt want anything but as i havce seen with modded cars its handy to have some guages.. also any ideas on where to mount them and does any1 know where i could get guages that would look simialr to the oem ones? i.e white dials and red needle? Thanks in advance for any help.
