I have a Paloma all I can say so far so good . Was real easy to break in, idle all day if you let it . Only have tried one pipe and that was a werks 2058 man she is fast . Easy to tune and I am not no tuning expert at all . I started with the 6.5 Venturi and was getting 9mins to a tank of gas . Changed Venturi to 5.4 but motor was not working to good . Probably could have tuned it to be better but I just put the 6 Venturi in and bang she was working as per normal . With that last Venturi change motor temps at 245 degrees and last 11mins to a tank of gas . All I can say so far has way more bottom end then my plus 4 I had , let see if it last as long .
