Got the bug you are correct, when PE installed and first drove mine Erik indicated it stumbled, he worked with Roush and they sent a new carburator. Erik installed the car no more issues. So from the time I got the car it has been perfect, (the way it should be) Major credit to erik at PE for identifying the problem and taking the time to inform me and correct instead of ship the car and we will deal with it later. I was going to install the engine and trans myself but when I read Roush warranty they require a certified installer, which I am not so I am very glad I decided to let PE do the work and therefore roush had no wiggle room. I always wonder how they would have treated me if I would have called direct after I installed. story may have been different. I will say this it is the best running engine i have ever owned as far as power and torque, I could put a glass of water on the air cleaner and rev to 4000 rpm and you will not see a ripple, incredible balance job.
