Hello from Thailand, I recently install a high grade FMIC on my SLK250 CGI the car already have Vath tuned chip producing 244hp and 360nm @ 2000 rpm. I was very happy with the low and mid range power of the car however the top end were pretty much nothing. However, after installing the upgrade FMIC i lost the pull on the mid range but gain a little more on top end. I felt the car is more powerful but it begins to lagg sometimes especially on hot days.

I suspect that i am also experiencing drop in boost too is this normal after installing big FMIC? I am curious wether i need to retune the Chip to accommodate the IC? Or is there any other upgrade to help fix this problems


I will upload the photo tonight
Thank you very much
