Hi i just bought a second-hand Liberty 3.0R H6 Spec B and the previous owner said that the modifications on it were a Full XForce exhaust system and custom Raptor headers. He said he wasn't sure how much power it makes and I was wondering if anyone had anything similar to me and knew how much power it makes. Im also aware that I should just go get it dyno-tuned and I can figure out everything through that but Im just wondering if anyone has an idea how much it makes. Its also automatic 5-speed.
Thank you
