Not to take away business from John (Sportbike) as I know that he is making some huge showerheads, equal to stage 6 I believe, but the Bully Dog 5's I'm running now are real sweet. I had Sportbikes email addy but somehow lost same, if you can't find it through other sources, let me know and I'll do some searching for you. One word of warning though, these babies will turn the day into night if you really get on it with low boost. Also, Bully Dog recommends fuel line upgrades, i. e. , either drill out or loose entirely your banjo bolts and you better have good fuel pressure before you add them as well, they can really drag it down on WOT runs, even with the Mallory pushing and the Aeroquip fittings. All that being considered, they are still 'streetable' IMHO. I still run with the EZ on the most aggressive setting and can do a somewhat slow start with not much smoke, same as the 3's were but a bit more sensative to the throttle at low boost. Give Bully Dog a call and ask them how much to upgrade from the 2's to whichever you wish, they gave me a $500. 00 credit when I returned the BD 3's. Hope this helps !!!
