I did a custom map 6 before with Terry.. Nothing special, all default map 6 settings that you should verify on the website (sorry don't have link handy). All I did was add less boost at the beginning, +1 All across the board. This was before we all figured out that it was the general boost limit (and my intake) that needed to be raised so I could go back to keep 1 or 2. Again... Map 2 for some reason has better throttle response and behavior, as well as the max boost. Even if I could get a little more out of the custom map (which I can't) then I like the daily driving behaviour of map 2.

Terry originally wanted me to do the ewg plugs too.. But I suck and couldn't get to the plug from the top. When I changed the tire for winter in did notice the box through the wheel well and I thought about trying it again, but I didn't remove the splash shield and it was still pretty tight and decided it wasn't worth the effort again

At this point I'm really interested in that mid pipe ( or to get an front splitter for looks ). We'll see! My front pipe does look exactly like the setup you have on your 2 series.. Just the bends hopefully it's the same... I do want more pics of your install before I pull the trigger!
Yeah I beleive our pipe is the same as the part # on real oem is the same for both our USA models.

I plan to install the midpipe in a couple weeks just too much pollen out now .

I don't have my bms intake in rite now I have the bmc drop in filter from Italy ( k&n style ) at the moment .

I running map 0 rite now , think I'm gonna go back to v18 firmware. V19 was great in the colder temps and car loved the DWP setting in the winter but seems to be pushing boost up to high in the hotter temps .

I may just go to map 6 and do a 2 psi flat boost additive across the board .

Thoughts ..

Turned DWP back to zero. No more boost spikes but all is still good as t had been for months. I do agree with DWP at 70 the car pulled more but peak boost was higher and hit 30.5 via my AEM gauge and no fail safe kicked in. Now I am back to predictable. Staying with latest firmware though.

Hey JB4 users has anyone tried using map 6 ( custom map ) ? Curious if anyone has tried the flat boost option in map 6 , thinking a 25-26 psi flat boost would work really well .

Warmer weather and DWP off. Hit 30.2 spike a few times, consistent 26.5ish. Car still great!
