71 Duster 360 turbo build
Did some fuel tuning today and AFR’s are looking great. I’m suddenly having issues with boost creep though. Removed my boost controller, but boost didn’t drop to 14-15psi as expected. The car also felt a bit slower, but I figured that was the taller tires. Turns out that table switching had been enabled the day I updated my injector data so anytime I went into positive pressure it switched tables and provided me with only 10-12 degrees. I did almost kiss 20psi though, and I now have plenty of injector for it!
I’m hopeful that the low timing is the cause of my boost creep. The diaphragm in my wastegate is clearly on its last leg(some melting) so I won’t be surprised if that’s the actual cause.
Boost cut set at 225kpa
