Recently flashed 6MT Stg 1 of 5-23 maps. Was running Stg 3 with FMIC, DCI and downpipes (etc) until I reverted to stock.

Doing a quick datalog I saw that my Wastegate comp value was +5.0 %, remembering the Shiv tuning guide I adjusted the boost control gain from 45 to 40 % and reset the WCV via the Command Center.

After this I went for a data-collecting run to see how well the car was adjusting to the new values, in short, it did not like them. As soon as I got on WOT in 3rd CEL flashes on, at the end of my trip I have the following glorious codes:

12140 2f6c exhaust plug
12003 2ee3 cooling gradient plausibility (Tune related?)
10706 29D2 cyl 6 misfire
11327 2C3F o2 sensor code
11328 2C40 o2 sensor code
10720 29E0 fuel mixture code
10721 29E1 too lean.

During my runs the exhaust note was 'strange,' if you look, the boost curve is completely whack and not linear at all, after going WOT it would sit for two seconds before boost kicked in full.

Again I was running Stg 3 with no issues prior and when I removed the procede everything went back to normal.

Is there a problem running that low of BCG via the tuning software? Did something else go wrong?

When you reverted back to stock, did the uninstaller accidentally swap the bank1 and bank2 front o2 sensors? That would explain the o2 sensor/fuel mixture codes and general poor running.

On another note, if your wg compensation value is pinned at +5%, you should *raise* your boost control gain from 45 to 50. You went the other way

Mixing the o2's would have been easy, but there weren't any codes/running issues when I removed the procede.

Now I wonder why I thought I should drop it, memory must be going. Thanks for the tip Shiv.
