one particular tuner told me straight up that superchips used to be top of the game, that they were really on the ball with the bluefin when it was first released, and their maps were up there with the best of them, but that lately its no longer the case. of course this could simply be a case of 'buy from us because we're better than they are' but his arguement was that: now days everyones brining out hand held switches, and with this being the case, most people can go to a reasonably local tuner and have a custom map loaded to a switch, rather than me for example, buying a bluefin while living in northern ireland. i cant exactly nip across to superchips hq for a custom map, and a generic stage 2 map will always struggle when comapred to a custom one, so yeah its all down to whats local to you that you can trust- i had no local option, and superchips was the cheapest of two i would trust to work- superchips and revo.
i would bet that if you got a custom map at superchips hq on their rr, optimised for your car with whatever mods it may or may not have, and then loaded that to your own bluefin, your car would hold its own against the likes of vrsy's-providing yous have the same mods etc.
but, if your not local to superchips, then your stuck with a generic map, not ideal for your car, but an average map to suit the average tfsi, and so you probably wouldnt compare to vrsy.
Tuners like superchips and revo etc all have massive experience which goes a long way, and they all produce great products, but the maps will differ according to the experience of the tuner.
reviews from people like vrsy are always helpful because theyve got experience of the different products out there-superchips revo and now shark.
if your only thinking about stage 1 then one is most likely as good as the other, what you really want is a reputable company which offers good value for money comapred to the opposition, while offering similar power levels. its only if you are thinking of going stage 2 or higher in the future that you might think about the option of a custom map-in which case youd be better off picking a good company within a reasonable driving distance
