7.3L SHUDDER SOUND.....HELP PLEASE

Just wondering here my 02 F 350 7.3 seems to make a shuddering sound at around 90 kms plus or when under heavy load or going up any steep hills at great speed...The truck is modded, AFE stage 2 intake, chipped gauges & 4" turbo back, any idea whats causing it and how to make it go away ?


Thanks

that being said then with he wicked wheel, that should still work with the cold air intake as well correct?

Are turbo surge and compressor surge the same thing ?




that's the noise i am getting with it

Thanks

100% wicked wheel will fix your problem... that sound is your turbo trying to suck more air than it can handel , cause the compressor wheel is to small.. this is verry bad for your turbo an can break the shaft.. spend $80 on a wicked wheel an problem solved..
