210bhp i think is a bit optimistic, as i know that the injectors on the PD 150's only go to 225bhp before they reach there limit, most remaps will get a region of 170-195bhp....
Past that its unrealible power and most proberly unrealiable RR results....
Most if not all remaps are good, i think the main thing is where you get it from eg, near ur home that way if theres any
problem u can have a quick drive back to sort it, and also the price... as most have the similar results......
I personally have a AMD remap and its more aggressive than my friends Revo and Jabba maps, but in that it led to a short life for my clutch and therefore clutch upgrade was needed within basically 6 months...
As you know the searchy button is great
help, search for the nearest VAG tuner to urself and head down there and have a look, all remaps are good as long as it has somewhere to go back to if something does (god forbid) goes wrong!
EDIT: if its on a FR
Ibiza, no chance on a 210bhp rise on a SMIC.... no chance....
