MBWorld Fanatic!
Woah woah woah...there's a Pure 1000 now? Where was I when this came out?
Website doesn't list a lot of info. Anyone have more info on them? Are they a drop in replacements like the Pure 900s? Or do they require modification to install?
I know you said they're similar to the turbos Yabeela sells; if I recall correctly, you can clearly tell Yabeela turbos are aftermarket just by looking under the hood (vs Pure 900s which look like factory drop-in replacements).
Also, I know it says 800rwhp on pump...but is that on a stock fuel system, including fuel pump? Cuz it was my understanding you're running outta fuel around 700rwhp...? Hence the Spool HPFP upgrade...

Yabeela sells PTG turbos under their own brand name - PTG is the turbo manufacturer, and Yabeela (was) the exclusive distributor for them at the time - that’s no longer the case it seems. PTG turbos are based off Precision 58/76 ball bearing turbos, not the hybrid/stock frame turbos that Pure offers (800, 900, 1000).
PTG’s are the better buy than the 1000’s IMO because they’re priced the same, except the PTG’s don’t require your stock turbocharger cores since you’re buying brand new turbos. It’s a much better value and gives you all the headroom in the world with a modern ball bearing CHRA.

It’s not completely clear but how does a TCU tune impact the 7spd MCT clutch longevity? From previous platforms, a “DCT” tune actually did not affect longevity as it optimized shift points and reduced clutch slippage even though line pressure and clamping force are increased.
Obviously power is a major factor (I’m running PTG1000’s and catless DPs) but I’m determining if doing a TCU is worth any potential risks of ripping through a transmission (only 9500 miles) at these power levels. Already had to replace a transmission (in an M3) in the last 24 months.
I just want to understand the negative impacts/risks (if any) of doing this.

How much power and torque are you putting down? If you're making more power than the stock transmission can handle, and you remove via a TCU tune all the electronically programmed limitations that were keeping the transmission alive, then you're likely to end up destroying the transmission. You may need to beef up the internals of the transmission to take full advantage of any benefits to a TCU tune with your setup.
Is there a known power limit that the MCT can handle on a daily basis?

I would also expect that a TCU tune could be added that is customized to your setup. Allowing more torque than the stock software but still keeping it within the hardware limits of your particular setup.
