1.75" is the OD? What's ID of that hose? (would be same as the turbo housing outlet OD) Just double checking. Thanks!

(and I PM'd on the purchase - already have the outlet covered ... so anyone else with a 135 or Z4 have at it!)

Oops I am sorry I skimmed it and assumed ID. Just the coupler not attached to anying is roughly 1.950 when installed on the outlet roughly 2.050. The actual ID is 1.650 Hopeful this helps.

Just finished up my daily gc 2.0 tune on 93 and to say the least I'm impressed, these gc's are really begining to show how good they are when setup correctly with the right supporting mods.

Still working on the e85 tune, still a bit to go.

Yes taking it easy on 93, we want a solid clean tune for everyday use and e85 for those odd days I just want to have fun and later blend both tunes on flex fuel map.

Yea MAF g/s is just a calculated value based on various complex models. It's very accurate for stock turbo cars, but beyond that should just be looked at as a number input as an axis lookup to tables.

Jake,
I get the impression it is also spot on if you leave BRO, and some other factors stock on an unscaled <22psi tune... Wouldn't you agree?

Correct. But again, only for stock turbos. It doesn't take fuel scalar or stft into account for the airflow model, and 19psi on stock turbos is much different g/s than 19psi on upgraded stock frames or an ST, they move a lot more air. Fueling can account for the difference thanks to it being closed loop and having a wide range to add. You see what I mean?

I'm amazed you guys haven't announced anything on the GC+ option.

I just got my set in and looking down the intake side of the compressor its a whole other animal compared to a normal GC. Is it just me or does the turbine look larger too?
