Wanted to reach out and ask for some help I have a 2016 GLA45 with the following modifications
Alpha high flow downpipe with 200 cell cat
Full 3inch exhaust
Pure 550 upgraded turbo
I originally had a stage 2 tune from eurocharged for the stock turbo and they were kind enough to include the base tune for the 550 turbo as well. Well the problem lies in when I installed the HPtuners it did something so that when I try to upload my tune from the MyGenius it wont do it saying that theres another tune on it because the hptuners uploaded a software update so that it could read the tune. Neither I nor eurocharge know how to fix this so the only option I have now is to utilize the hptuners editor and get a tune going that way. I am hoping someone here has a tune that I can start with based on the pure 550 upgraded turbo that I can log and improve on with the persons help. Im not sure how to do the mercedes tuning. I use to be great at the old 95-2002 LS cars but these mercedes are completely different animal. I was able to read the tune that was in the ecm which would be the eurocharged stage 2 tune for stock turbo. I wasnt able to put my stock tune in before this whole problem started. I am willing to pay for the help I am attaching my tune and if someone can help Id be forever grateful. I like an aggressive throttle very responsive, want it to pull as hard as possible to redline, I feel the redline could be raised safely to 6500 instead of 6250 but not needed. if you need my vin I can provide that as well.
Appreciate any help guys
