I have had my ic pump fail 100% it just stopped lost all power then had it chaged and it was going hard again.

Now i feel like i have started to lose power. My car is not pulling that hard dont no y could my new ic pump that mb dealer put in be starting to fail.?

could it be the pump is stuffing up but still working so the car is only pulling a little timing out and ther 4 im losing power?

also what psi/boost does a 03 e55 amg run standed

 

Standard boost is 11.8psi in 4th gear at 5500rpms.

If you have access to a scan tool with CAN BUS feature you can measure the boost while driving the car it will be the MAP readout you may have to convert it in psi.

Check the car in the morning to see if it is loosing power because when the engine is cold it should not loose power if the ic pump is begining to fail.
Let me know your findings I can help out more.

 

cool i will keep in touch i can get my hands on the scan tool so ill c what psi im getting that will help ill let ya know how i go

Thanks mate
