I am going to gap my plugs again this Friday as i did not check the gapping before installing.
I do hear slight misfires during deceleration, the plugs are brand new Bosch ones from pelican parts.
I will be checking for leaks as well I will also due some more logs tomorrow using a different program on my laptop as well as on Torque android app.

Finally was able to check for boost leaks fixed majority of them, was unable to fix the one that sounded like it was coming from the plenum. Checking my n75 valve today to figure out if it still works Todd told me this could be causing the advanced timing and also the boost spike.

I took a picture of my turbo/waste gate actuator not sure if they need to be replaced? Is it ok for the waste gate actuator to look like this?
