Ok,
COBB RMM is installed (yesterday)
Initial thoughts are all over the place.
First start; AC was on, high cold idle etc. NVH had increased a LOT. Inc small increase in exhaust noise generally also which was surprising to me. This general NVH increase was expected and I told myself that before the first start/drive. So no freak out, but it needs to be noted.
First drive was not ideal as a test, but I do think I feel some additional "directness" in the driveline as a whole. Which was the goal. 1-2 shift slightly improved (I have the already stellar shifter seen in previous posts above)
Did one"spirited" 1-2 pull/shift while going around a corner, and still got some inside wheel hop.
I'll report back once I have put some klm on the set up and the RMM has had a chance to break-in a little.
TLDR:
1: It feels good and does what it says on the tin mostly.
2: Downsides of vibes etc I suspect will diminish (disappear?) as the RMM breaks in.
