No transmission tune available for g30 yet so no point to upgrade turbo when you benefit nothing from it, currently runming stage 2.5 but cant handle all that power too.

DP and tune? You are saying the transmission on the 540 already can't handle that? |

true. I can't use full power due to torque limitations. I'm have VTT GC + Dorch Stage 2 HPFP.

Hey, I'm about to get the DS2 pump. How is it? Fitment (i.e. no modifications to stock components, sound proofing, engine cover, etc.)? Thanks!

Also, on your third photo, which part/how much did you have to bend the line which attaches to the HPFP? Was it a lot or just a little? Would I be able to bend it back if I decide to revert to stock HPFP? Thanks!

Based on what I've heard is that ZF8 in G30 and other B58's is limited to 550NM which is about 405ftlbs. When I dyno'd my stage 1 tune, car made 403wtq so basically with stage 1 I was already at limits. Stage 2 makes even more torque and for that to happen properly, definitely needed transmission tune to lift up the limits. That's one reason but xHP gives you so many other options and overall shifts are so fast, aggressive downshifting, throttle blips and much more.

Does anyone know what exactly the xHP flash does to the box? .. Is it just upping the limits or does it actually physically do anything inside (e.g. increasing pressures etc). I wonder just how safe it is and how this stuff reduces lifespan on the gearbox.

I've had it installed for about a week or so and it's been great. Shifts in comfort and unchanged. Sport+ have lightning fast shifts similar to DCT. The paddles also respond much faster than without xHP. IMHO, it is worth it for the torque increase as well as the faster shifts.

[EDIT] Never mind - just spotted your post in the other thread . Just ordered the MHD from Burger. Going to give this a shot myself once I get the BM3 Stage 2 & DP installed.
