am i right in thinking that throught the Data port under the steering wheel and a mechanical boost gauge (pipes and all) should read exactly the same? is there a difference in accuracy between the two? also what would people recommend? i'm only looking at boost nothing else, and would like to see peak boost after its happened (so press a button and see what i've hit peak) cheers guys
