It's now been 10,000 miles since switching to a single turbo setup, and I'm still daily driving without any issues. Temperatures have been in the high 90's more often than not lately and the 1er handles it with ease. For the past 5,000 or so miles I've been running 17psi on E20 fueling -- with great looking logs. No timing drops in any cylinders, no fuel pump drops (high or low pressure), and boost comes on hard and stays rock solid right at 17psi. Any more boost or any more ethanol, and my HPFP can't keep up. Everything else is holding up well and the Blackstone Laboratories reports keep coming back with good news.
With 110,000 miles on the odometer now, I've finally acquired all the parts to address my struggling fuel system. While my old parts worked brilliantly with a lot of ethanol on stock turbos, they simply couldn't keep up with all the newfound airflow. The new setup will consist of a Stage 3 bucketed LPFP (two 450s, the second on a 15psi Hobb's Switch) from Fuel-It! in the tank, flowing through upgraded Fuel-It! fuel lines into an ethanol sensor which is integrated into the JB4 Mobile App, into the camlock fitting y-line from Fuel-It! - one end flowing into the Phoenix Port Injection manifold with JB4 PI controller, and the other end flowing into the HPFP, which will be brand new.
Once I have all that up and running, I'll probably link up with a professional tuner to dial in something around 23psi on E40-E60 for every day purposes and continue to DD and maintain everything until the wheels fall off. Until I can install all this hardware and iron out all the kinks over the next month or so, here's some more photos:
