[s-cars] Wastegate Spring and IA III+ chip

[Adam Cramer]

I backed it all of the way out (can't turn to the left anymore) this
morning and the stuttering seems to be gone.  I will try to tighten a
few turns and see if that improves boost without causing more
stuttering.

How many turns is max?  

Anyone know IA specifically?
