Do you know if it is the injectors or the fuel pump that is maxed out or both ?
I was looking at a Jeep Trackhawk before i put the deposit for a used 2019 GLC63 that i will pick up right after Christmas. It is so easy to make power on those
but they do not handle as good as the Merc.

Im currently at 600awhp and it seems the fuel system may be maxed out. I have the water meth kit just havent installed it. The system is really falling on its face though on anything over my current power

Thank you,
Eurocharged it is. I might be looking for bigger turbos in a year once i make sure the car is running good before i start messing with it.
I know you have some nice build with bigger turbos. Do you know at what WHP the fuel system needs to be upgraded ?

Either Renntech or Eurocharged.

I am currently with Eurocharged and I am very happy with the product and the customer service. Renntech and Eurocharged are the same performance. You will be saving $300-400 going with Eurocharged.

Hi,
I am in the process of getting 2019 GLC63 and probably will tune it in 6-12 months. Would you recommend a tuner that you had good experience with and not running the car very lean as per your spark plugs thread ?

Thank you
