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.

Both logs show pretty lean fuel trims with the 2nd log showing the long terms at +25%.

Could be losing fuel pressure.

My exact question, why would the first thing you do be adding the speed density OS?

All you can really do is just add more timing in the spots that you cruise in, simple as that.

Be aware that a 2002 computer is a P01 and a 2003 computer is a P59, so some of the things you are putting into your 2002 computer may be wrong. The hummer would have been drive by wire and yours is...

Technically all airflow/fueling calculations take that number into account.

So if you left it as a 6.0 but went to a 416 cubic inch motor, you'd be skewing all your numbers to make it right....

Yeah, 100psi won't let the injector work right. See what it's like once it's back down to 58ish.

Whats your fuel pressure?

Those fuel trims aren't doing so good, they look super lean.

Also this tune file is for a 4.8, you'll want to copy over in 5.3 data for cylinder volume, VE tables,...

Just so you know you have the PE enable at 87% throttle and on the last 2 logs I looked at, you never once even hit 87% throttle. That is why it's still showing lean on the wideband.

How about you...

I personally go to around .4500 for shift times at part throttle and go down to .3000 at full throttle. Most shifts end up being around .3500-.4000 with my heavier foot.

Also if it's still on a...

You need to change more than just the flow rate data. The min injector pulse, short pulse adder and the offset data still needs changed.

This isn't a small block chevy either, no need to command...

No, HP Tuners can't flash all 8 segments that are required for something like that. You'd need to use a GM tool for something like that.

What you can do is find a 6.0 and use the compare feature...

Have at it lol

Not that simple. You need to swap the reluctor wheel on the crankshaft and swap the cam gear. It's not easy and it's not cheap to do.

And that's only those to things that are different, we...

Sending the computer in is not required on a 2018 Tahoe, you can buy 4 credits and tuning it like you would anything else. Just need to be connected to the internet the first time you read the file....

Fun fact, he payed for the tune and has every right to post it online because he payed for it. Unless you lock your tunes, which isn't fair to the person paying for the tune, people should have no...

I prefer the Pontiac.

31lb/hr or larger. You can use stock 8.1 injectors or stock flex fuel injectors from like a tahoe/suburban, those are 33lb/hr.

Some guys use the later flex fuel injectors which at 50-52lb/hr and a...

What specific vehicle are you working with?

That's a big camshaft for a stock stall converter and you need larger injectors before you really start tuning this.

For the time being you can increase the idle rpm to 750-800 when warm. Add...

I got about tree fiddy, is that enough?
