Has anybody used vagcheck for remapping and lightened flywheels? Any good?

Now then all, im buzzin as ive just got a lot higher paid job and one thing that i want is springing to my mind and im gettin excited!! Which around £250 map is best?? vagcheck claim upto 35 hp gains VagCheck , i appreciate that this is prob at the flywheel but would it make a hell of a lot of difference to the performance (know the answer just wanna get excited agn lol!). And also ive seen a dramatically lightened flywheel which if i remember correctly is cast alloy and weighs abt50% less than th standard and they reckon it gives abt 8bhp and it was fairly cheap£70 - £80 my cars also comin upto 60k so need to be thinkin abt changin cam and water pump anyway so may purchase if info is correct. Any help or advice wouldbe cool ,cheers, Vin.
