I think I could get 100 bhp out of it, I had a DAB edition and that was 100 but I guess you might be right theres very little in it, 25 bhp probably wont make a ton of difference. Anyone got any tried and tested methods for getting a little more power?

I don't think that there is any thing that can be done to improve the 75PS engine - its a lot different to the 100PS engine.
 
I think that 74 bhp was the power of my 1.4 polo 8v. If so it should pull well in the lower mid range but not have much at the top and no real point of red lining it. You need the 16v for that as the gti 16v (i guess 100bhp) they lent me once really flew:D

Once you know how to get the best out of it and work the box it should zip along around town nicely.

Well when I ordered the 1.4 SE Polo for my wife I also thought, "only 75PS from a modern 1.4 16V engine - should be very driveable" - wrong, it needs a bit of pushing but does seem to work okay sometimes.
