Hi,I think from a tuners point of view you have to assume most people who want more power from their R56
MCs will go the
JCw route anyway as it seems reasonable value,therefore its important to design products that work/compliment (add more power) to these cars as well as stock examples.Therefore designing a GTT remap & GTT cat back becomes lower priority .This is very much in contrast with the old
MCS where most tuners designed kits to compete against the
JCW. (us included) Mind you we cover both here as we do upgrade kits specifically for cars already fitted with JCW210 aswell.
