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.

You need to put in the 3 bar MAP sensor settings, disable the rear o2 sensor codes and COT.

Always post the tune you are working with, best way we can help.

In my opinion, running in the 12's on E85 isn't that lean at all. Running 11lbs of boost isn't a ton compared to what others run.

I'd be commanding around 12's in the alcohol table but that's just...

It will be just fine.

Good tune for what though?

Stock vehicle or what is the setup?

All I can really see is that it's a G6 with a 2.4 engine. It must take you forever to repeatedly try to take this thing to 127mph,...

How much power do you plan to make?

The 3 bar sensor should be 312.50 and -11.25 if I remember right. The data needs to be correct for the sensor.
