since then the car has since seen alot of tuning on pump gas in the 500-600 rwhp range.This is what the car was built for.2530's and GD manifolds have proven to provide a wider powerband but the GD manifolds were not something anybody new about at the time the motor was being built and were not available till after it was running. Obviously nothing Z1 does is going to impress you and I'm not sure why you spend so much time posting about something thats a "disappointment".Instead of ending your post with "nevermind" why dont you just not post on the subject at all.I might add that the owner(whom you dont know) and those who have actually had experiences with the Peacemaker have been very happy with the car and more often than not shocked at its performance.
