So I picked up a new '17 last Tuesday. By Friday I was stage 1 with the Cobb OTS 93 OCT Stage 1 map (waiting on my Stratified map). I have yet to go WOT from a dig and run through the gears. Well today an opportunity arose where I "needed" to do such a thing. My god the 1-2 shift was frightening!!! I thought the ****ing motor was ripped out of the car there was such a bang and jolt. I can only assume, and hope, this is due to the factory RMM and is why everyone changes it? The 2-3 shift was no where near as violent. Please tell me this is the crappy stock RMM so I can replace it and on the occasion I run through the gears I don't have to worry about ripping the engine from the mount.
