PS2

paul223 · 02-27-2019, 08:27 AM

Another PS2 going in, PS1 coming out. 2013 535i, current mods Wagner intercooler, BM3, XHP, K&N cold air intake, Downpipe, high flow inlet, M Performance mufflers.

I wonder what is the difference in cold side turbine. Old had six blades.

Good luck. My ignition coils showed their weakness so having them replaced today. I did lpfp stage 2 diy and now I get "power of fuel pump too high for the actual pressure" so I might go back to stock lpfp.

Another thing I am running into is "air mass too high" i hope it is something the tuner can fix or I will blame either my tmap or the k&n intake at this point.

nice. Make sure you add the turbo inlet from AZ-Racer

It's annoying that Pure continuously change their stage 2 turbo without publishing anything about the changes. Full blade compressor wheels are supposed to only be better when used in combination with an anti-surge compressor housing. There is a reason BorgWarner, PTE, MHI etc all use 6x6, 7x7 or 5x5 compressor wheels and ALL Garrett GTX turbos have anti-surge compressor housings.
