I would be interested to learn more about how REVO achieve these results and whether any of these effect the component lifespans ?
Me too - but I don't think Revo would be too keen on giving away their hard earned 'trade secrets'.
e.g. increased torque limit , hows that done? (pump pressure I believe), will kit reduce the life of the pump?
higher rev limit , is the std drivetrain up to it? (edit : valves / pistons / rods etc )
how much extra does this extend you mph change points?
I think the publisised 'torque limitations' on the 6-speed DSGs (max 350Nm) have been well and truely dashed - what torque is Hurdy now pushing?
Regarding 'pump pressure' - I don't actually think they can increase the oil presure - I reckon what they do is simply increase the speed of actuation of the electro-hydraulic valves and pistons (which 'release' each clutch pack). I doub't there is any change in speed in which the actual gear cogs engage - because the DSG works on a 'pre-select' principle.
And onto the potential damage to the engine (valves, pistons, rods, etc) - well these will be protected by the rev-limiter in the
engine ECU - so the DSG remap shouldn't technically affect this.
also would you recommend a DSG oil change prior to having this done?
As with anything relating to modifications - if there is any potential likelyhood of said modification affecting the durability or longevity, then a reduction in service intervals should be highly advisable. So in real terms, if you have an engine remap and a DSG remap, and drive according to proscribed performance gains, then I would personally strongly recommend halving the DSGs standard scheduled oil & filter change from 40k miles down to 20k miles. Don't forget, on a standard DSG fluid change, you don't actually completely drain the box - there is still a residual of just under 2 litres of the old fluid in there (DSG fluid change is approx 5.5 litres, whereas full from dry is 7.2 litres).
