boost help?!
 

so i think i know what the problem is, ive had two dealers look at it and one diesel shop.. but this is whats happening. i watch my boost gauge, and when my psi gets above 25.4, it goes insane and throws codes such as the icp sensor and waste gate... turning on my engine light. the first two times i took it right to a dealer and they couldnt find anything wrong.. so them two codes keep getting thrown and i just clear them and it is fine. this normally happens when i get going above 60 and then go up a really big steep hill pulling a heavy trailer or if i am racing.. what im asking is, what exactly is going on and what do i need to do to fix this problem? :argh::argh::argh: thanks for any help

I have heard of people using a boost fooler. Has it always thrown codes or just recently?

just since ive put them mods on

It's probably throwing an overboost code, which will happen when the boost gets to a certain point... This will tell the computer to start defueling the truck...

Do you happen to know exactly what code was thrown?

Sounds like surge to me, plus overboost...


Thats turbo surge on a 7.3...

ya the codes thrown are: icp sensor uncontrollable, and uh.. something with the wastegate i dont exactly remember that one cause sometimes it throws two or three for the wastgate

csipsd, i think your right on the turbo surge part, which ats housing should i look into?

And ATS compressor housing will fix your surge issues...

its been a while since ive chatted with you on here.. bout six months lol.. so pretty much that is what i need to fix my problem?

Your surge issue for sure... The other codes you will need other repairs.

The overboost code... Fix...

Riffraff Diesel: OCR - Overboost Code Regulator

The ICP code is from running a tuner, they will cause that code when your tuning asks for more ICP then the HPOP can give.

im gonna have to get the one with the wastegate that pops up every now an then.. what aftermarket of that should i get?
