I have just purchased a Gruppe M second hand off another member on here. This didn't come with a fitting guide as he got it fitted by a tuner...
I was wondering if anyone had an electronic copy of this, as the link on the official Gruppe M website doesn't work at the moment.
Hello to all !
Today I was on dyno for check, how it really works this GruppeM.
I have very bad news for owners and potential buyers.
GruppeM DOESN'T WORK and this is NOT a joke.[smilie=pissedoff.g:
Joke is that GruppeM claimed 14hp with Hondata, but its 'a bull****.
I have mesured my CTR 6...
