pulled my camper last weekend for the first time with the powerpup(50hp)quad stack,with the quad race box on 60 hp while pulling a hill peddle to the floor I could get to about 45 mph and its like I hit a wall,would not go any faster,egts would not go over 800dgs.done this on two hills with the same results,for the third hill I switched the quad to 100hp setting and it felt like it was gonna rip the tongue off the front of my camper and my egts quickly hit 1250 dgs.To me it definately seems like a lack of fuel issue,could it be the 60 hp setting on my quad is funky,or could it just be the stack,by the way it's a 8000lb camper.
