glafond - that was my problem as well. I even had my trip meter go to little lines

.

I am running a 4" exhaust (no cat) and Superchips on HP.

But I just got it back from the shop, new head bolts and gaskets

I figured I will just keep her at the economy mode now.

F350 FX4 running 33" BFG's.

My F350 V-10 will run all day at 80mph while pulling a 10,000lb trailer.

My car will do 178mph at the track.

Same problem, head gaskets & bolts were replaced... much better now.
the economy mode wasn't the solution, i still had to tow my 30' 5er, i never towed it with the predator installed, always went back to stock and ran with the "tow mode" engaged. It still blew coolant. haven't towed again. (michigan.. no camping for awhile..) but i have "tested" the truck in predator mode.
haven't seen any coolant problems. YEAH!!!

132mph and i had to shut her down becaz i was climbing up on a car.the first time i took it to 100 it restarted at 0 and i got real real scared i broke the speedo or something.i doubt i had more then 10mph to top her out. i cant believe how much these trucks pull at all speeds. alot of people are prolly gonna get mad when i say this but i hit 100 just about everyday i drive it to school because theres this open road that stretchs 3miles and no one is on it at 6am. call me crazy or just being a kid

I have yet to tow with her but I always put it back to stock. I hope that fixed the problem. Are you running the predator in HP mode?
