I went on my first long trip with my new Grizz towing a small trailer with 3 sliding windows for my deer stand. I was really pleasantly surprised at the MPGs I got compared to my old TRV 1000 Cat. Since I was comparing my Grizz to my old Cat I really missed the POWER or that feeling……………….I thought MAYBE I could cut the spark arrester out of my Grizz’s muffler and weld on a bigger tip, but before I do will I be needing a fuel programmer (all this lean talk has me VERY nervous) will this even give a power gain at all or just add noise?

Thanks.
