With no other changes to the 06 truck in my sig, all of a sudden it wont spool the turbos anymore, while being stopped and powerbraking it!
It would spool very well before lunch, now there is no way it will spool. makes 2 psi max,

While driving it has great power, makes 60 psi like normal.

Engine, turbo or tranny problem? we put in new TC and VB bout a week ago.

 

what kind of t/q did you put in

 

What do you mean?

torque management 1
Torque Converter, a Goerend

 

Sounds like an exhaust leak or boost leak.

 

Sounds like you blew a boot off to me, I would check for boost leaks if I can find the right thread I will post it on here how to do it.

 

I dont think its a leak if its hitting full boost on the street, try turning the Torque Management on 4 and turn the shift defuel on

 

I was going to say overfueling but you said that it just happened after LUNCH with not changes. I had the same problem at the track. I turned down to lvl 7, tq 2 and now it spools great. There is a updated program coming out that will take care of the overfueling.
When the T/C on my stock tranny got weak I could not power brake for the life of me, it would just sit there and smoke and never spin the tires.

 

check for soft codes,when i throw an overboost it doesnt set a cel and kills my bottom end boost

 

I did't see that you could get 60 pounds at speeds sorry.

 

without the W/TM and the defuel off I could not build more than 10#....with wild and no defuel....the sky is the limit!!!

 

engine is getting a little hotter even at cruise now,
it seems to miss a very little at idle, and it looses coolant???

 

I was going to tell you in the other post to think about Opie's Bypass!

Can you see where the coolant is going...? In the oil, or leaking around the head gasket?

 

i cant find out where the coolant goes! oil seems to be normal at safe level,

dont know if its pushing the coolant out of the radiator cap... anyway, i have to refill it after a short normal drive...

Does anybody think there is a problem with the seats? or a cracked head? id hate to take off the head again, but i´d do that once sure!

 

Try the torque management settings in the Smarty first. Also I see this happened about the same time you put in a new converter. Dave makes a great converter. I wonder maybe if it is too tight? What is the stall speed? Again this is no way a shot at the converter. They work great.

 

Sounds like a head gasket issue. I would check to see if a wastegate is stuck open first.
