Hey, good runs! 2.2 60' times is good with street tires for FWD, but I know how our cars are; they come off the line ok, then the tires start spinning like crazy! I have no idea whats up with my car, I've got to get it to a dyno or something. My boost does the same thing as yours though, it will spike to about 13-14psi, then fall down to 11psi. It's gonna be ugly seeing that boost gauge spike to 20psi when I'm trying to run 15psi soon, I know I'm gonna break shit But hey, good times and I'm gald to see another turbo 420A getting some times!
