A 2006 6.0 truck with drive by cable doesn't exist, they are all drive by wire.

Why no post your tune here so we can look at it to see how bad this tune is and maybe see if they really shut them...

You are in advanced view under the EDIT tab right?

The Baro settings is below the MAP settings you already put in for the 3 bar MAP.

The injectors requires the flow rate, min injector pulse,...

I've seen some weird crap happen when people go to the 2 or 3 bar OS's. The numbers go from the max of 640 to over 1,000 for whatever reason. Seen that on many tune files on here.

The brake tq mngt needs to be set to 0.

Minor thing, your open loop EQ ratio needs to be set to 1.00 for operating temp, you are tuning to stoich for outside of boost, your data will be wrong....

With that limited amount of information you aren't going to get much help. Be more detailed with all the mods, what vehicle, what fuel system and all that jazz so we know exactly what you are working...

You'd have to make your own spark tables for flex fuel, they don't populate themselves.

I did notice that your stoich table is wrong, not a huge deal but it's still wrong. 0% alcohol isn't 14.1,...

I would go to like 1.135 or 1.130 on the EQ ratio. That is a little leaner.

That's basically like what I was doing. Going from in your case 12.6 to 12.9-13.0 AFR.

Obviously a dyno would be best...

Something is wrong elsewhere if you started with trims at 45-50%, that is not a tuning issue.

There should never be values in your VE table over 100 like you have, you are working around an issue....

No, I don't. I run leaner with E85.

This is my truck but I run in AFR terms 12.3-12.5 on gas and around 12.9-13.0 on E85.

Codes P0297 and P0299 are still on, those need to turned off with catless headers, plus the cat test is still active on this tune file. People that run the newest software can't remove those things...

I asked for the tune to make sure you turned off all the correct things for the AFM delete.

Past that you can raise the idle from 525 to like 650 and they always smooth out.

Post the tune.

Also if you didn't replace the lifters, you did it wrong. You can't run AFM lifters on a non AFM camshaft.

The nice thing about HP Tuners is that you can try something and change it if it doesn't work.

Start with a regular flex fuel table and see what yours trims do, then change it if needed.

You can't command a stoich ratio of 13.3 if the fuel you are running is not that. The stoich ratio must be correct for the fuel in the tank, there is no fudging numbers with that. Return the open...

Hey now, I feel attacked. I do have 2 vehicles and I do only drive one of them to the grocery store :D

I see it in the channels list, so to me it's being logged.

Who the hell put the stoich for the fuel at 12.92 if you are running 87 octane fuel that is maybe E10 at most.

That is totally wrong.

54-58psi of fuel pressure is totally fine. Adding fuel to a stock truck with a stock tune is just masking a problem, something tells me you still have a vacuum leak somewhere or exhaust leaks from...

I'd buy a lot of stuff if I had a big enough yard to put it on.

Likely it's something that becomes a mismatch between values between two different systems that work together. But that is just a guess as HP Tuners is only able to flash the PCM/TCM and nothing...

Honestly just start with a 5.3 timing table because it's a 5.3 engine.

That tune file still has the MAF working, so you aren't tuning in just speed density for the VE table.

The majority of that log shows the trims are negative, so it's rich and not really lean. I...

Two things I want to say.

What is your fuel system like. Return or returnless? What is your fuel pressure?

And you need larger injectors on a 6.0 with a camshaft that size. It's going to run...

You're fueling must be too rich while cruising if you are fouling spark plugs. Without a data log with a wideband, I can't really see how it's running.

Just where it starts to lean out.
