I sure have no problems with the attitude box or the 3 other turbo 1000 that ride with me. we have a setting that runs good and clean and when I go to pull a long chute I change 2 numbers . no big deal and have 3,200 trouble free miles like this. Back to the topic I love the turbo 1000 had a boondocker 2 injector ride with me a lot and it ran ok but 5.5 lbs was its max and sure wouldn't run with the 4 injectors 1000s another one started out as a boondocker but got twisted and it runs good. My cutler runs good and these are the 3071 turbo a 3076 twisted rides with me and also runs good once you get your tunning figured out the turbo 1000 is a blast, they are like a dragster waiting for the green light
