Update on the Equilibrium Tuning custom tune of my GTI, still with the Shuenk IS38+ turbocharger. The last update to the tuning progress was when I had decided that fuel pressure was not staying as high as I wanted and so I decided to install an HPA high pressure fuel pump. Before installing the pump I took the GTI to a dyno session to capture stock fueling performance.
Since making those changes I have probably been the slowest customer that EQT is working with, taking longer for me to provide them with my datalogs than it takes for EQT to turnaround a tune revision. Frequently having my car apart to try different parts has a way of impeding progress.
Tuning has been going well and I feel like there is light at the end of the tunnel. Showing some solid boost performance as illustrated in the chart below:
