LML Will not build over ~22PSI of boost

Yes I have maxxed out anything related to air flow and turbo control with only a bit of luck. Maxing out the egt and compressor maps I was able to keep the VVT at ~30% and get a bit more response out of it, but nothing like I would like to have.

Try rescaling the MAF sensor, lie to the ecm, If I have time I might try that later, it is definitely tied to either MAF or turbine shaft speed as not matter what the power levels are at when the ecm sees 420+ g/s MAF Flow it goes to 0% vane position.

25#s still seems low..... does the truck have a EGR blocker/delete? Cause can't the EGRs still blow open on the LML?

I just sent mitco39 more maps.

We'll see what we can do with them- if anything. They are definitely vane related and one is temp based. OS50 and 44 are nightmares- complete different from each other and OS 94 and 49. Might be time to start building tunes for all year trucks on the engine parameters of OS94 or 49.


If you rescale the MAF at higher RPMs and play with the smoke tables you should be alright. I think only the smoke tables use the MAF values off idle...can anyone verify?

I think it'd be easier to play around and fool the ecu first- then when we have an idea of what we need we can hit the binary.

I will get logs as soon as possible. Thanks Dustin, you know your stuff!
