This is HOW the HHR SS is supposed to run when it's running correctly with the GMS1 upgrade. It hold's the boost VERY VERY well. All of the power and torque is there. It sets you back in the seat for sure.
@dadocda This is just the Stage 1 Tune. With the Trifecta Tune....I hit 27 lbs....but on either tune....sometimes it will act 100% fine...then other times...it will stumble and fall on it's face.
