Cobb stage 2 35xdrive build thread.

[Jyohay]

I'm running a Cobb on my n55 x5
Just out an ER downpipe on, and I. Stage 2 I'm getting the same boost as stage 1 which is about 9.5.
Cobb said both the maps are the same just stage 2 has DTCs off so no CEL comes on for the downpipe.
Since these off the shelf maps are really for the e9x/e8x platforms, and the e7x has a considerably larger intercooler, I decided today to load up the stag 2+FMIC map.

Guys, holy
17 PSI and loving it.
With my bms intake this thing is howling and the downpipe sounds awesome.
I came from a 335 with jb4 (but I did switch to Cobb for a short while) and I had an FMIC and Downpipes so on Cobb I never tried the non +FMIC maps.
On the n54 with jb4, you got more boost with map 2 which is for downpipes then map 1.......but on Cobb on the x5 n55 it seems to not be the case.
I never tried anything but map 2 aggressive +FMIC on Cobb on my 335 so I do not know the behavior.
I'm just puzzled as why anyone would install a downpipe for stage 2 if the Cobb tune isn't going to give anymore boost.

Yes I know.
I'm prob the only x5 35xdrive owner with a downpipe


I beat a e90 jb4 335 map1 and a f30 328 jb4 map 1 in a pull tonight.
