Hello folks,
Don’t know how I got here but Whatup!!
I’m a daily driver f32 n55 setup. Currently running stage 2. Bm3. I enjoy turning wrenches, not really!!! Just hate paying Dealership prices. All has been well with stage two for 50,000 miles, like I said Daily Driver. I now have 77,000 miles. Recently did bunch of maintenance.
Motor mounts
Water Pumps
Thermostat
Oil pump housing gaskets
Oil cooler upgrade
Radiators upgrade
Ngk plugs
Precision Raceworks coils and wires
Drive belt, tensioner and idler pulley
All coolant hoses and coolant changed!!!
After work preformed I had not so great idea of trying to flash/download transmission tune. Wasn’t available when I originally tuned my vehicle with bm3 stage 2.
Was told I could do with cell phone.☹️☹️
Wrong!!! I couldn’t that is. Long story short DRIVETRAIN MALFUNCTION!!!!!!!☹️☹️☹️
Vehicle Transmission locked in park.

I will not bash anyone , after much frustration, weed, and the grace of god! I was able to un flash reflash new software!
NOTE:NEW SOFTWARE.
Back on road all seams well. No codes, no leaks. Couple thousand miles go by, then to my suprise I noticed a misfire at high rpm.
Only time I experience this is when at cruse speed and downshift and ask for power. If ask for power from slow rool no issues.
Sorry for being long winded, spoolstreet made me post this😁. Any insite into my misefire issues would be greatly appreciated. Again this is only at high rpm under load , oh and no codes present.
New plugs ?
New wires?
New coil packs?
New Tune?
Where to start, I’m stumped. Thanks !!!!
