They do advise when purchasing the software to buy an aftermarket induction kit, the R600 is good for 600 bhp the same as theirs and they do look class under the bonnet compared to standard and sound awesome [emoji108], there are other alternatives thou, take it to Rtech for a custom map and you could leave all the hardware standard with the same results if not more bhp and torque, i had my gti ed35 mapped by Nicky took it from 235bhp to 313bhp no mods at all.
