So, what was wrong? How did you repair it?

 

Swapped out the DVs and replaced one of the air pumps.

My tuner would have laughed me off if I sent him a file with a max of 5400 rpm. Oh wait, he did....

Looks lean by the way, but who knows whats happening up top. Also, if you can use 4th even better

 

Yeah hard to do a full pull around here especially a 4th gear run.

Just go to a 1/4 mile track and do a 4th gear pull. I have done that before. Short shift the first 3 and hammer 4th

 

lol that works too but not very practical if i'm going to be data logging all the time. closest track to me is ~2 hrs. away

Just came up on this thread...
not sure why your logging lamda set point, maf, or 02 ahead of cat etc...
you should be logging:
RPM
engine load
ignition angle
oxygen sensing , actual value bank 1
oxygen sensing , actual value bank 2
boost pressure of sensor...

this will give you what you need... Im surprised no one even brought that up...

yes your boost is low... .6 bar is low... the only way to test for most issues is a pressure test from the turbos... are you sure you successfully loaded the program.. maybe your still on stock ecu...

 

210 east at 2 am, there is several places to test and tune along the way

 

well, we also don't know what the idle pressure is either so can't really say what actual boost is....is it 1000, 900? what? he needs to datalog from idle to see starting pressure. I would guess it is 1000 but that is just a guess.
