Ok, so feeling a little bit more confident today as it relates to the newly installed ATP turbos....
Amongst all of my chaotic running around all morning long, extending into the early afternoon.....
I got on the car hard, and even managed two separate, and distinct, WOT runs with her today.
Happy to report the car seemed to really like the newly bolted on power, and monitoring my boost gauge alone during those two WOT runs, I clipped just past 18psi which is exactly where I was at with the stock turbos, and my current dyno tune file I've been running from LMS.
I noticed no issues regarding the car shuddering, or jerking, or any other detracting type of occurrences, as if there are, or were, any fueling related issues.
Stoked about that, for sure!

Car noticeably pulled harder in the mid to upper RPM ranges. Much more so than with the stock turbos.
Once again, I can only imagine that these experiences will increase ten fold (or more) once I get my butt back out to LMS for a new dyno tune that would compliment the latest upgrades.
My deposit's been placed in the "Hard Hot Pipe" Group Buy which 4DR is running, so the proverbial ball is rolling on that......
Things are coming along rather nicely and I am very happy thus far.
Not to mention just eliminating the smell of that little bit of oil that was expelling from the main seals on each stock turbo, and dripping onto the catless downpipes / exterior housing of the turbos themselves, is truly much appreciated.
Just wanted to provide an update, as I said I would.
Happy motoring fellow Ecobooster's
