Alright guys, so the bushings in my Mountune RMM cracked after about 9k miles. I decided to give another RMM a shot, with 2 main goals in mind: I wanted something more aggressive than what mountune offered and I didn’t want anything crazy insane that would vibrate the cheap plastics in the dash apart. After a bit of research I decided to invest in a Whoosh Street Spec RMM.
Install was a breeze, a quick inspection side by side with my mountune proved that they were of nearly identical quality, with the edge going to whoosh because who wants to deal with 3 washers and a separate spacer (PITA to line up on install, and I’ve had the mountune out and back in at least half a dozen times in the last 5 months due to creaking). Everything snapped together, tolerances felt tight, and Ron provided torque specs via email (btw, that man has to have set a record for email response time it was uncanny) and I took her for a quick spin since it’s late.
Start up:
Additional vibrations, compared to the Mountune piece, were immediately noticable but they were hardly what anyone would consider harsh. Primarily felt through the steering wheel, these calmed down quite a bit when the engine idled down to 850rpm (or whatever the stock idle speed is). 900-1000rpm appears to be the point at which the vibes hit their worst, and again this isn’t even anything that made my change in the cup holder make any noise. Turning the AC on or off made no significant change to the vibrations in my opinion and frankly I was impressed before I even drove it.
Driving:
This will be brief for now, since I took it on a quick 10 minute drive. All I can really say is wow. Gear changes are buttery smooth. The car moves with a confidence that I don’t know was there even before the mountune cracked. Rev matched downshifts were significantly easier to hit and I wasn’t getting punished nearly as bad for not hitting the exact rpm.
Conclusion:
The Whoosh is better. Better than stock, better than Mountune. I have no idea what the warranty looks like on the Whoosh, but honestly Ron has responded to three separate emails within 15 minutes. Meanwhile mountune has required numerous follow up emails to tackle an issue that I provided photographic evidence of over three days ago, and I still don’t have any shipping information. The mountune RMM, when working, was essentially an OEM plus part. It was marginally stiffer than what Ford bolted up to the car, and in my opinion Ron has the RMM setup as it should have come from the factory. Absolutely will not hesitate to give Whoosh a shot when it comes time to do the next upgrade.
