I have a 2018 mt82 with the Roush 2650 phase 1 kit. I’m quite happy with it. It won’t ever be a 900hp monster but I don’t need that. I did modify the heat exchanger system and built an Aluminum tank. With the canned Roush tune and the heat exchanger water chilled with ice to about 55 to 60 degrees, the car made 657hp and 594 lbs ft of torque on a Dyno Jet. I was hoping for a bit more power, but torque falls off past 6k rpm.
Any feedback on max hp with a canned Roush tune? Wanting to keep the warranty.
