Always been told this to be correct, but remap alters the mpg figures on trip and have proven it before on my car.... in standard spec, the avearage trip mpg was within 0.5mpg whatever driving (long motorway/short town), now and have seen this on other cars too the mpg is roughly 5-7mpg out to the negative, its never consistant either it varies depending on driving style to how much it is out....
I always wrote down my mpg and compared to actual, did this for months after i had the car and then compared after remap.... my trip average over last 3 fills was 38mpg and as you can see below its nearer 34!
Not sure if its the same with the autodelta box but the mpg figures quoted looked too good to be correct...
