I have over a gallon on my Buggy Mod P5. Way more power than my OS V-Spec, XZ-B and JQ (VZB Speed) I've ran before, and 2-3 minutes more run time than any of them. Bottom end is very smooth, but it has a lot more mid range and top end that I'm used to. It runs much better on an OS P4 than the Werks 5 or 6, and solved my flame out issues. 2058 pipe, Buku clutch, really liking it so far!
