HELLO NEW TO THE BMW WORLD SO PLEASE BARE WITH ME ON WHAT IM GOING THRU.. SO IVE ONLY HAD THIS CAR

I WENT AHEAD AND GOT THE APP APONG WITH THE CORD YOU MEED TO PLUG INTO THE CAR OBD. AFTER TUNNING IT ON THE STAGE 2 TUNE I NOTICED A SLIGHT DIFFERENCE IN POWER BUT NOT WHAT THE YOUTUBE VIDEOS MADE IT SEEM LIKE. A WEEK GO BY AND I DECIDE AFTER READING THERE HAVE BEEN N54 OWNERS THAT USE ETHANOL E50 MIX WITH THE ETHANOL TUNE SO I WENT AHEAD AND FILLED UP AND TESTED THE FUEL AND IT WAS E50 ON THE DOT AS WELL AS TUNNING IT AT THE PUMP WITH THE STAGE 2 TUNE E50 MIX. I STARTED HER UP AND LET HER RUN FOR ABOUT 10 15 MIN AND WHEN I DID THE FIRST PULL FROM A DIG AND OMG!!!!!! THIS THING HAD TO GAIN 100+ HORSES I MEAN IT SPUN 1st 2nd AND LET GETTING INTO 3rd AND DROVE THE REST OF THE WAY HOME BUT OF COURSE DOING SOME 40 50 ROLLS AND THIS THING WAS HITTING 16.9 BOOST ON THE MHD GAUGES AND TARGET WAS 21psi OR SO I DONT REMEMBER BUT YEAH (SO THIS CAR BTW IS NOT MY DAILY I USE IT ONCE OR TWICE A WEEK) SO AFTER GETTING HOME I PARK HER AND ON THE WEEKEND I TAKE IT OUT FOR A SPIN WITH THE WIFE AND DROVE JUST LIKE I LEFT HER THE DAY I TUNNED HER AND WAS ON BEAST MODE. ON OUR WAY BACK HOME I WAS AT A RED LIGHT NEXT TO A HELL CAT REVVING ITS ENGINE I DECIDE IM GOING FOR IT SO I HOLD DOWN THE Dtc BOTTON FOR FEW SEC AND SLAP THE SHIFTER ON SPORT- DS -ON THE DASH LIGHT TURNS GREEN AND BEFORE YOU KNOWN IT THERES GAP ABOUT A BUS LONG AND IM ALL SMILES NOT SURE IF HELLCAT NEEDED DRIVER MOD OR WAS DADDYS CAR BUT I KNOW FOR A FACT THAT MOTTOR SCREAMED WHEN LIGHT TURNED GREEN. FEW LIGHTS DOWN I FEE LIKE THE CAR IS BUGGY AND SLUGISH WITH NO TURBO BOV SOUND AT ALL SO I PULL OFF AND CHECK THE MOTOR FOR ANYTHING BESIDES THE USUAL AND NOTHING SEEMED OUT OF PLACE OR BROKEN. I TURN IT BACK ON AND BAM IT SPOOLS WHEN I FLORED IT AND RIGHT AWAY GET HALF ENGINE WITH THE CODES I MENTIONED ON THE TITLE OF THIS POST. ITS BEEN ABOUT A WEEK NOW AND IVE LOOKED UP AND RESEARCHED ONLINE TO SEE IF ANYONE RAN INTO SAME ISSUE AND NOTHING IVE CHECKED EVERYTHING AND WENT THRU VACUUM LINES,SENSOR PLUGS AND CLEANING THEM,PRESSURE TESTED LINES , TUNNED BACK TO STOCK THAN BACK TO STAGE 2 AND STILL I GET THE BOV SOUND ON FIRST REV THAN NOTHING WITH HALF ENGINE LIGHT COMING ON AS WELL AS CODES I MENTION PRESSURE SENSOR AND BOOST DEACTIVATION .. TURNING CAR OFF THAN ON SEEMS TO HOLD BOOST IM ASSUMING SINCE BOV SOUNDS WHEN GIVING IT THAT REV BUT AFTER 2 OR 3 REVS IT GOES AWAY.. IVE RESET ADAPTATION AND CLEARED CODES IDK HOW MANY TIMES PAST FEW DAYS AND EVEN DROVE IT ON FIRST START TO SEE IF WHEN IN MOTION IT SOMEHOW GOES BACK TO BEAST MODE BUT IT JUST PISSES ME MORE OFF AND I GO RIGHT BACK HOME RESEARCHING FOR HOURS!! I IVE NEVER JOINED ANY OF THESE PAGES AT ALL FOR ANY CAR IVE OWNED BUT AFTER SEEING HOW MANY ARE GETTING HELP ON THESE PAGES I GIVING IT A SHOT AND PRAYING SOMEONE CAN HELP WITH MY STRESS LEVELS RISING.

Welcome. And first tip for you to improve the help you get. Make it easy for people to read...

  • Dont use all caps
  • Use some paragraphs or other spacing in the text
  • Include code numbers with the error description

This will likely be a minor problem so stay positive šŸ˜Ž
