I upgraded my chargepipe, boost pipe and DV with FTP and Go Fast Bites on my 2016 F25 N20.

I also have a BMS JB tuner.

I can feel the difference. Turbo lag is all but non-existent.

Yeah lag is terrible stock.

BMS will increase pedal response to the throttle/ecu.

DV+ diverter got a spring, so it will bypass the pressure under 2 circumstances :
- solenoid position (open/close) its binary, there's no between, aka ON/OFF.
- DV+ is spring loaded. that means when the solenoid is open, doesn't mean that the diverter will let 100% air bypass just like OEM. it will ''hold'' a bit of boost, so shifting are less laggy.

Can't tell if it really does a difference on a ZF8 since there's a lot of gears and its fast in comparison on a 6 MT transmission.

On my 6MT I didn't really tell a difference, but on paper it should do the trick.
0.01 more on the s 0-60 ?

Anyway, one thing sure, the DV+ is stronger than the oem membrane, so its a peace of mind.

How hard was the diverter valve to install? Thinking about doing mine or maybe just wait for PS2

on the n55 its next to the water pump. hard to reach.

If you're planning to do the water pump, it might be a great idea to do the DV in the same time.

I even might think it's not possible with the water pump in place, someone need to confirm. I did the waterpump on my x3, but I didn't change the DV.

I had my indy mechanic do the install...….he said getting the third and final screw into the DV+ was a pain but doable (closest one to the turbo). He stated it would be way easier if he had pulled the turbo out...

That looks damn near impossible with the water pump. I plan to do the water pump when I do PS2 so I suppose i'd just do the DV then.
