not got vag com to do it however it did have a faulty lambda sensor changed when the remap was 1st done and didnt really make much difference.awsome said it was healthy too looking at the graph.
the original map they did wasnt right car was bad to drive then after re doing it it seems that they have reduced the boost and doesnt feel as fast as it should.dont get me wrong it feels quick.they also said it had a revo trial on it b4 the remap.i dont think it was a trial tho.i think it was a remap because it feels not much quicker than from day 1ive had it and back then i thought it was faster than it should having driven a friends std lc the day b4!!!
ok, trying to pick out bits from what you have said....
if they have reduced the boost, for what ever reason, then yes your figures could well be right BUT
what is the reason they have mapped your car at a reduced level of boost? heat soak?
still as I asked earlier, what are the differences they advertise as stg1 and stg2 or the differences in maps between the cost of £399 - £750
things do not add up right now, and charging £750 without knowing the different levels in maps, "looks" like they have charged you the full amount, but what exactly for?

As I said, dont take the 209bhp as gospel, as figures on the day come down to a lot of factors like ambient temp, RR conditions etc etc. It could well be right
Also on your graph, where is the peak power holding till? i.e. 209bhp @ 5000rpm?
