Well I have had my Boomba RMM in now for 50k+ miles and have been very satisfied with it. No squeaks...No rattles or anything out of it! Been rolling a Gen2 GTX2860 on it as of the last 5k. Almost 300whp + or - some HP depending on the day and road surface, Its a great piece from Boomba! There are a lot of choices out there now all which seem to be good quality poopa for your FiST. If you don't have a RMM ...I suggest buying one...totally worth it ...i was my First mod! Glad I did it! Thanks Boomba!

I had it for about 85k miles. AC vibes nothing too bad. Now onto the CPE rmm. One of my first mods too! [drinking]

I had that thing for less then a week and traded it back for a Mountune RMM. Hated every second I had it on the car. Did make it feel awesome when doing runs though.

PS, TQ Solutions RMM takes a shit if you have too much power

Mountune rmm just started creaking again... thinking the bolts are coming loose, again. As much as I love it when it’s quiet, really considering either boomba or Cobb if I have to pick the car up every 2 months to tighten this thing.

I am curious to see how all the Powerflex stuff feels in conjunction with the CPE. All I really want is no engine movement [raceflag]

if you grease it up it doesn't make any noise, I gave mine to a buddy and lubed it all and hasn't made another noise.

I had used a general multipurpose grease the last time, slathered all of the contact point on it. Lifted the car to check torque values and both the bolts are at around 60 ft/lbs (I say around because I use an autozone torque wrench). Next week I’ll see if I can actually further disassemble the motor mount itself and see if I can grease whatever I can take apart.

I got a Boomba RMM on mine.

At first, it vibrated pretty noticeably at idle.... Basically all the time. Once it broke in, its actually not bad at all. I only get a vibration at idle with the AC on. Not an issue for me though. It made shifting and driving so much more enjoyable.

Solid 9.5/10

I highly recommend Mobil 1 grease. You can get it in a 1 pound can (as well as a tube), and it works great. I got frustrated with having to constantly re-grease the sway bar bushings on a previous car -- I switched to Mobil 1 grease and never had another issue. I have used it on the FiST from day 1 (as well as a bunch of other projects) and I haven't had to re-grease anything yet. Good stuff.

I just hit 1000 miles on my FiST with the Boomba RMM and I have to say the shifting is way more solid and as RubenZZZ said idle with the A/C on there's vibration but not hardly noticeable at all for me ..
Definitely something that Ford should do in the production line . [wrenchin] [driving]

Thoughts on the race RMM from whoosh? Strongly considering purchasing one.

It's actually great, first startup there was some vibration I've used it a couple of days and those vibrations are practically gone. I also have the Race upper Trans mount and the Street Engine Mount inserts. Car feels real solid and a lot better then it did with the Torque Solutions or the Mountune I used to have. Also no were near as harsh as the Boomba RMM

my friend greased it inside where the bushing sits
