Mein Auto: BMW M Power
Soon after swapping to M50 injectors, my car wouldn't idle in D and was surging in P, but ran like a champ above idle. It felt like I had a massive vacuum leak, but I had to drive her to work and back, and in a few days, the issue had resolved itself. She idles great now.

Robert at E30 MotorWerks clued me in to the fact that the OE M20B25 injectors are 14.5lb. It takes the DME 75 miles or so to adjust / calibrate to the M50 units.

Finally got around to swapping in the new/rebuilt M50 greenies. My blue tops looked similar to yours but not quite as bad.

Sweet Jesus. If there was some learning going on in the DME, I wasn't aware of it. I felt the extra zippiness right out of the gate and on two fill ups I've gotten a bit more than 23.5 mpg. Never got that high before. Was usually 21 to 22. Not a giant improvement but I will take it with a big smile on my face.

Thank you MEPEH. You put out a fine product. I should have done this years ago.
