What are you commanding? With aftermarket boost applications, total spark is between 9-15. Its not as high as a stock forced induction calibrations. You might have Spark modifier removing some timing

This question isn't really answerable with the provided information. What fuel are you running? What is your Lambda? IAT? ECT? etc... There are situations when that could be good or bad, but with the given information that's impossible to tell. Have you asked your tuner?

With no more boost & fueling on this in the car. I would be looking for a diff tuner for sure cause the only reason that tuner is telling you to do SD tune is for him to play & him get more info to help him only on some big HP cars for him not to look so stupid..
