It can even be installed with the subframe on. Install guide is on my site under the install tab, mmp-e.com

Great numbers guys! Looks like diegopiedra could benefit from a bigger FMIC with that increased flow!

Why is the torque so much lower than the other?

The tuner was purposely tuning to limit torque to save the stock rods from bending. 650wtq with low end torque is the limit for stock rods. Also with all the low end torque the turbo make, believe me you don't want more, it's already super hard to get any traction at all with LSD and drag radials in 1st 2nd 3rd

Interesting. I've seen dyno graphs with almost 800wtq. I have never heard that there is a stock rod limit for these cars.

I agree that its a handful with that much torque, but I have seen 10" slicks work wonders.

There's cars making less torque at earlier RPM's that have had bent rods/cracked ring lands. The rods are definitely the weak point in the N54.

Easing the boost to limit low RPM torque is a great way to keep the engine alive a bit longer.

Diego repping MMP stage 3 turbos in some Mexico runs! Racing his buddy with an M6 773whp/845wtq. Even until the end he tells me he put half a car on the M6

I don't have an exact count, but over 40 for sure, a few of those are international

Almost 60 sets shipped now, all but a few installed. The turbos are selling very well and performing even better

I'm trying to get one of your customers to run, so we can see the difference of twins vs single

So 40 cars are driving around with your turbos, or you've sold 40 sets? That's way more than I was expecting, nice!

I think this is the first post with results I've seen. Would definitely like to see more!
