okay so i have a m dub tune. When i am driving my car it doesnt want to boost any sometime and sometimes it runs fine for a bit then goes right back to no boost... if i pull over and restart the car it runs fine for a bit then does the same thing. What could it be?

I have a cel for map sensor being out of distance or something and bank 1 is running rich. Could it be running rich due to the map sensor? The cel comes on and off. I have a forge bpv and it flutters until i hit boost then it is normal. I have greased the bpv.

 

map or maf yes

 

those cels coming on will make the car automatically limit boost. You need to figure out what's wrong.

Get some MAF cleaner from your local autoparts store. Clean your maf, and map sensors as a starting point. Sometimes oil blowby can foul out the map sensors, and the oil buildup can make it throw a p0106 for the map sensor.
