Not your every day problem here

[all-boost]

I have a heavy truck and tow alot with it .
It's stock small cam lq4 with a 72 q-trim ball bearing turbonetics.

Towing weight it's great but time to time I'll haul something that is a wall in the wind.

Problem is when I have a wall in the wind and running highway speed it will stay between 0 and 2# boost constantly which I'm fine with but.

Anytime I am in boost at a steady state the truck will shut off .
No sputter or whimper the pcm shuts it off .
It comes up with a map code that I haven't caught the number because I'm usually on a busy highway when it happens and I have to clear the code to get going again.

Unless im in boost at a steady state it has no issues at all .
It is 2 bar sd tuned .

I'm sure not many are in boost at steady state so hard to find anyone having the same issue .

Anyone know what to adjust to get it to be ok with over 100kpa in steady state ?

If I back off and go back in it to keep from being steady it never dies.

At wot it's also fine .
Only in steady state .

Forgot to mention it's p59

Think I found it .
Engine diag / airflow / p0106 calculated map max .

Being I was between 2400 and 2600 rpm at 30 to 40 % throttle and over 100kpa it didn't agree.
I set entire table to 200 kpa because this thing will go in boost at low rpm.

The steady state only issue is most likely when in lockup it would run lower rpm but still in boost .

Will see how it goes .
It sucks shutting off in highway traffic

You defintely found the problem. It's a common thing. I maxed out the table early on.
