hey whats up man. i saw ur post on this thread: https://mbworld.org/forums/cls-coupe...-ecu-tune.html

i have the stage 2 AMR tune and weistec catless DP. I have 90 degree 02 spacers on as well, however i keep getting CEL and the only code showing is P2099. You had mentioned something about DMing you to see what you did to get rid of the cel?

I got the stage 2 tune BEFORE putting on the downpipes as a FYI. I have cleared the code a bunch of times and reset the ECU one time so far, but after 65 miles of driving, the CEL and the p2099 comes back, thanks man.

I'll buy it. Assuming you have the box please let me know what the shipping was after the purchase. I can send $135 now via paypal if you are up for transaction. Whatever I paid over the actual shipping, you can simply refund me the difference.
