Well I haven't run meth yet but so far with just water it has done a fairly good job of keeping the egt's down. I never get above 1350 towing 10 000lbs through the mountains so that's good. But a week after I installed it, the pump started leaking from the body between the pump end and motor body. I'm currently working with Labonte on a repair/replace thing but I haven't had time to look at it-too busy on vacation fishing the salmon in Cambell River!!
Supposedly they are coming out with a frame mount tank as well and I am definetly going to get one!! The 6gal in the box sux!!
