It may quickly flare higher, but I don't see it on the boost gauge.
I've checked over everything - Map sensor contact with the A/C compressor, all wires are soldered - may have to revisit that once it gets warmer and re-do them, checked for boost leakdown.
Going to switch out the yellow spring for the green spring next. If that doesn't work then I'm planning getting it tuned via HPTuners.

Our group is planning on that this spring also. Sure there will be a learning curve but with 6 SS's in the group, shouldn't take too long to dial them in...
Maybe 7 hey Paul you wanta tune that thing yet ?

Popped the yellow spring in to see if that helps the mid range throttle occasional bouncing. Test drive gave me 25lbs with no flutter from a 60mph roll, 23lbs no flutter from a 40mph roll and reduced fluctuating while accelerating from a light with mid throttle. No flutter at any poiny and no CEL yet (knock on wood). Mine may be liking the yellow.

I am in the process of learning the hptunes.
Should be running a hptune early spring myself hopefully.
