Hi all, I have a c200 kompressor 1996, it's the first version without variable camshaft and 132kw, so I put a 220mm pulley 4bar fpr k&n filter cold spark and relocated maf, naw I have 1.0 bar boost, I need to clamp the maf by a zener 4,7v diode but the car don't push well over 4500 to 5700g/min and its the second maf that I broke, I think the maf can't resist the new airflow, I also measure the volt from the maf (not clamped for this test) and it arrive at 5,3v the dead. Can I use a different maf? I read about the 0280218062 maf (BMW m3 3.2 maf) that can ne used on the m111 kompressor motor, its a good idea? Please help me because I don't know haw can I solve my problem.

p.s. Sorry for my bad english, I'm from Rome (italy)
