APR DTR6054 Direct Turbocharger Replacement System

Easiest way is to log the mpi injector PW.

Do you know a way to see if the MPI is even working? Low side pressure says it’s at 5 bar. Don’t know if the mpi isn’t working at high load or it’s the in-tank pump not supplying enough fuel. Sucks I have nothing to log with but I do have a brand new Cobb lol, but won’t be able to use it.

2016 S3. APR DTR first street hit after last revision by Matt at EQT. I’m true e85 and the issues I was having is the APR 305 pump that they sell is trash and can’t even keep up with their MPI. Here is the aftermath of a EQT brushless swap and a fresh EQT tune. I should be able to get a 10.7-10.8. Once it gets colder here in Florida and the DA drops.

Any CEL issues with your IE downpipe, or are you running a spacer?

This was that same pass

That's a really solid run! Cool to see what this thing can do with a real tune and some E, not many people posting times for this turbo in general

Yeah I have a CEL due to EQT tune and second 02 removed. Otherwise with IE downpipe and other tuner I never had a CEL show up after 1-2k miles

I’ll be at EuroWars as well and get the Hoosiers on

Are you satisfied with how the DTR is performing on your custom tune? The APR stock fueling map is atrocious of a powerband until I get the fueling done.

IE downpipe was always insta CEL on my car.

Yeah, I never got a CEL with DTR APR tune with IE downpipe, I was expecting to to pop up after a hundred miles but after putting more than 1k on it, never came up lol

 

[MQBGOD]

And I even ran it open downpipe for hundreds of miles no issues

I got a fun little science experiment done earlier with a newer (2021+) Mercedes-AMG GLE 63 S. Mattle black. It looked and sounded nice. I'm surprised I even kept up with it given I'm still on stock fueling. I don't think it was modded - downpipe and tune - as I've been behind a GLC 63 S with a downpipe and it was much louder and gurglier than this GLE. I always wanted to know how I'd stack up against one of those or an X5/X6 M Competition on a highway. The Trackhawks I come across are always modified and on residential streets. We don't condone science experiments in densely populated areas.

Stock downpipe is a restrictive piece of sh*t though. I'm fortunate the tune didn't pull power to protect the stock cats this time around.

Update: EQT MPI, EQT LPFP, EQT 5-bar sensors, EQT 93/E85 tunes incoming…
