E89 Z4 - VTT Stg 2+ EK build
Been collecting parts in my garage for a few months now. Just waiting on my installer to get me on the schedule. Figure i would start a thread documenting the process (hopefully everything goes smoothly)
Here's an inventory of everything going in:
Also happening at the same time:

Why water pump and thermostat at such low mileage? Are you putting in higher capacity pump? I'm also updating clutch due to slippage

Water pump and thermostat is cheap and no additional labor since the turbos will be out. Side note: purchased the Motiv dual pump surge tank. http://www.motivmotorsport.com/produ...e-tank-radium/ decided to overbuild the fuel system a bit to be on the safe side. This is the same setup that single turbo motiv Z4 is running.

Congrats on the numbers. Now, do you realize you are triggering a Torque Limit Active ? I can only imagine what your post shifts will look like.

Absolutely. I can tell you now your shifts are taking a plunder, and the DME will pull load to drop your boost. Its very very very bad for the DCT. If not careful when shifting your tranny can perm slip causing the engine to over rev and boom. Same shit happened to Terry when his DCT slipped.
I am shocked how everyone on the BB site did not point that out to you. TLM = Torque Limit Active is usually 4 but you have a 2048 spike. There is a lot of scaling in your map that the DCT does not like. Whats going to happen when you shift the DME will reduce your load and timing and you will feel something aint right like how it use to shift. |

I did go to a 1/2 mile event today and got hit with a ton of shift bog... Maybe related. It was annoying as hell. It pulls like a frieght train till you shift then it falls on its face

If your map is not locked I could probably fix the shift bog but that's up to Jake if he want to work with me or not on it if he can't resolve it for you.
