Wierd puking problem??

[Powerstrokin250]

Truck started puking on me under high amounts of boost 30-40 pounds so i took the tuner out and put the stock exhaust back on the truck and brought it to the dealer... They pressure tested the system while cold and while it was hott held like a champ... So i change the coolant cap and still puking... Any i deas??

Any help is much appreciated guys!!

[kaya@bernhausen]

egr cooler maybe. just a possibility

[Powerstrokin250]

The tuner i have turns off the egr... But if it was bad wouldnt it have failed the pressure tests??

[kaya@bernhausen]

the tuner only disables the egr valve. exhaust gas still flows through the egr coolers.
depends on how bad the leak is and how long the test was run.
any white smoke out the exhaust?

[Powerstrokin250]

No white smoke and no leaks just puking under high amounts of boost im so lost man

[Powerstrokin250]

If it passed the pressure tests the head gaskets should be good right?? Can it still pass the test with a bad egr cooler?

[strokinpower]

no, its you Head Gaskets. I had the exact same issue. Only puked on high HP tunes running balls to the wall. Took it in they said nothing was wrong. It kept doing it. I finally took it to Rudy's and he did gaskets among other things and no problems since.

Damn i was hoping i could just do the egr delete and make it stop but it looks like ima have to sink some money into this thing

[Powerstrokin250]

Can i just creep around at low boost for a while until i can save the money? Or will it hurt it

[strokinpower]

no Rudy told me he drove his for a year before studding it. I would just run it on a lower HP setting and dont do any boosted launches or anything. What tunes are you running?
