vibrating noise
When idling my pickup makes a vibrating noise i hear very well from inside the cab and dont hear it as well in the engine compartment is there it only does it at idle either in gear or park but under power no noise just wondering what all it could be its the 99 f250 with 278k 4x4 thanks

Mine also does that. Did you change your CPS lately? I noticed after I switched the CPS to the blue international one. With the gray CPS it did not do it so I am assuming its a timing issue and it does it more in the colder weather here. They told me the blue one is nice but if you can get your hands on a black one before the recall Im told thats the cats meow. Havent had any luck getting one of those though.

Do you have an aftermarket exhaust, sometimes the pipe will rattle on the bolt on the trans cross member, done so on mine.

Let us know what you find, exhaust dinging is alot better than a tranny rattle, thats for sure. If you get a new tranny from BTS, everything gets replaced.

Thanks, I try to keep it clean. As for the turbo, yes, lower EGT's better throttle response but mostly top end, found that out last year at the track in Ten. To fully appreciate this turbo is to get a nice set of injectors, hybrids is what I'm shooting for, got a few other mods to do before that though. These turbos also sound very good and strong, sweet whistling sound, love it.
