my light came on the other day. i had just pulled out on the high way and was standing on the go pedal. the light came on for a few min and then went off. it did the same thing twice after that but only when i was playing around. do these trucks have egt sensors in them to give you a warning that your to hot?
It is basically a pressure regulator that limits the amount of boost that your map sensor sees. It will not give you more boost. Some of our site sponsers have them.
so will it hurt any thing if i dont get one? light in the pocket right now, just got 6.0 tranny cooler, up pipes,ccv mod and ss brake lines all the way around!
if it is a over boost it will defuel the truck..you will loose power till the boost drops bellow 22..not haveing the OBA isnt going to hurt anything...
IIRC it is around 22-23 that the map trips the ses light.
That's what everyone says... mine doesn't seem to kick in until around 25-26. Never noticed it defueling either which is weird, always seems to run just the same. I think my truck is just a freak
