I think you should stop adding more power. At that torque level, you are close to dct's limit.

You could add an upgraded FMIC to help improve power consistancy or meth to improve consistancy and get a decent bump in power when tuned for it.

Other than that your options for getting more power are going to get pricy. Mainly upgraded turbos...

You can just ask the guys to add a little more power if you want. You don't need a JB4 to add power to an AP tune. The AP is plenty powerful enough to tune the vehicle to the limits of your hardware.

If you're gonna spend more money on mods, just go get your ProTune readjusted for the new mods. It's unnecessary (and you won't maximize the potential gains) if you were to stack the JB4 on your custom made COBB map.

At those levels it's a matter of time until the trans starts slipping (non-MT/upgraded trans problems)

Posted in your other thread. AS of right now (without an authentic DCT upgrade), RBs + DCT = Trans Death (or replacing the clutch every XX miles like Drew who has the ESS low-compression, supercharged M3)

There is a bit of misunderstanding on this topic. The M3 DCT is programmed differently from the 335is, as the 335is produces substantially more torque than the M3 therefore the bar pressure is raised

We now have a DCT 335is around 480 wtq with no slippage. No one knows what the stock limit is on this car and we cannot go by example of the M3 DCT other than drawing a line of percaution as a guide.

It is mere conjecture at this point to assume a particular limitation based on experience of the M3 which is remotely programmed differently from the 335is

RBs in a dct would be fun!

Until your trans gives, but as BuraQ stated, no one knows the limit yet, you could be a guinea pig

exactly i have 463 tq an never expirenced any slips?
im going to order these rbs soon how many miles is the low compression ess m3 clutch lasting?
i can probly keep it lower boost maybe 500tq with more hp480 im aiming at

With RBs you should be looking at more hp less tq

It honestly depends on how aggressively driven the car is. If you're constantly launching & dropping the hammer from a roll in 2nd gear, then probably not very long.

I think Drew (DLSJ5) got ~10k on the low-compression before it started slipping really bad. But he was also putting 1/4 miles on the car & the high speed events (Shift Sector, etc)
