surging ? with quad.

[nick05]

any others with this problem? while cruising at 69-75mph with cruise off & quad on 60hp, i feel the truck start to pulse or hesitate at constant speed. if i slow down a little or mash it it'll go away. if it's on 30hp it won't surge. otherwise the truck never has died while crusin or stalled at idle. i've got a fp gauge and it stays at 15-16psi all the time. just wondering if i should call up quad to see if i should send it back. double checked all connecters & no codes.

thanks for any info

thanks for the reply. i read through that forum before and it seem that they have the problem with the cruise on. mine is not. i called quad and they told me to send back the box not the harness to reflash it. i shuld see it next week and then we'll see if that fixed it. otherwise i'll check that map sensor again just to be sure.
