I have a c180 kompressor and am currently looking into getting the ecu remapped from the standard 143bhp to 173bhp. I have been told in order to do this i need a smaller pulley and maybe a different belt! Where is best to get these from, what do i need and is it a big job?

 

Post first 6 numbers of your VIN:..., to let us help you.
Generaly, there are 5 ways(set-ups) to get more power!

Hi,
I'd mine chipped too! It's a 1997 C Class 200 T
VIN 2020802F670263

 

----------------------------------------------------
From your VIN,seems that your car it is not a kompressor,so you can have approx.154HP with a pack (part no:MKB 111 11) from MKB (camshafts,ECU adaptation,air filters,differenc. ...).
