No worries, for the price you may experience some remapping of the fuel flow parameters to make it more responsive, but power gains will be minimal.
I used to have a B6 4.2 V8 S4 and with a Milltek non res, racing downpipes (track only, ahem, no cats), removed inlet flaps, Cold Air Induction kit, and Mihea from MRC fiddling with the ecu, the car went from 344 to 372...
Didn’t really feel any different, however, my god it sounded amazing though, like an Aussie V8 touring car, it screamed!!!
