Excellent explanation. I have a question Darkiedm4. My M235i has PS1 and JB4. I have this issue at mid rpms where as you can see the car tries to up.to 17 psi (Map7)but then something happens and the EWG opens.... but then... try to close again.

at the beginning I thought it could be pump gas pressure so I tried to Map5 and the issue was the same but just at 15 psi.

what do you think about this? what could be?

Hard to say without seeing data log of the runs.

Definitely needs logs to compare.

Random Question - Is there a Difference in the Pure Stage 1 and the Dinan upgrade turbo kit? is dinan just sourcing them from Pure and re-branding/selling it? Are these a vargas turbo? Just curious. Lots of positive feedback about the Pure turbo set ups.

IIRC Dinan does not source them from Pure or VTT.

Pure has been great so far for our customers. Biggest thing about Dinan that is good is it's CARB compliant. If that's not a concern (which it likely won't be since you are in Canada) Pure is another great option.

Most guys go with PS2 though since the itch for more power will always be there. You could always run the PS2 at a lower boost and have that extra room if you so desire. My .02

I'd recommend the PS2 unless you are really 10000% set on a stage 1 upgrade.
