So if driving hard to the red line in an 'Chipped TT', your saying it will better the MPG that doing the same in an unmodified one? :? :?
We talk about reliability of the engine as a whole, but no talk what about effects on other ancillaries, like turbos, clutches, gearbox, brakes, tyres.?
no, if you thrash it mpg will suffer just the same, possibly worse because the map wil probably increase fuelling at WOT. But a better map broadly uses fuel more efficiently so driven sensibly should return better mpg. If the remap makes the power and torque curves broader then its easier to maintain speed under a wider range of road conditions with less throttle and/or gear changes so again, compared to a standard car under the same conditions, mpg should improve... and the evidence proves this...
However, there are maps that pull a lot more torque/power but in a much narrower rev band... these maps are more fun to drive, give more of a kick in the backside, but require much more gear work to keep the engine/turbo on song and will return worse mpg unless the peak is close to where you cruise on the motorway... these maps are better suited to the track... tuners like VagCheck and p-torque can provide alternate maps to suit individual needs but some of the more aggressive can be pretty undrivable in UK road traffic...
Of course more power adds wear to other components like brakes etc, but only if you use it all the time. For me a map is something to enjoy when the opportunity arises - on the track or, like the other day, tanking over the hills from Huddersfield to Rotherham

(where I met another 225TTR being driven by a nun, or so it seemed... :? )
