could someone look at this tune let me know what yall think it almost died when i let off gas and i want the cam to hit harder lolchop chop.hpltune34.hpl

Thats 2 logs we need the tune file...
Are we suppose to just guess what camshaft you put in the engine?
Also are you going to bother to fix all of your error codes you got going on too?
You have like 13 o2 sensor codes being thrown right now. Turn off the codes you aren't using anymore like the rear o2 sensors and fix the front sensors. You have a barely working bank 2 sensor 1 right now, it goes between 450mv and sorta kinda working. Your bank 2 fueling is all over the place because of it and you need to get a wideband oxygen sensor for tuning, that is the only way you will get your airflow model correct.
This thing is going to drive like shit with how you have the timing setup for your chop tune and with fueling being off, it'll be worse.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
dude im so new to all of this not even gonna lie lol an i have a wide band on the way an idk why my o2 aint working both new with good reading ground and power an i have no clue on how to use hptuner almost at all lol an its a stage 3 btr cam long tube headers ported 706 heads 660 valve springs ls7 lifters but yes im use to like 1990 an under lol carbs an stuff
so should i add fuel or what i just need it to run a little better till i get most of my stuff in so i can have ass drive it to work lol

Do you know how many different "Stage 3" camshafts there are?Originally Posted by Stubby601
You should wait till you have the wideband in before trying to change anything.
The best thing to do is take the dumb ghost cam spark swing out. Get fueling, spark, and idle all tuned then go back with the silly ghost cam stuff.
And you have 706 heads on a Gen 4 engine with flat top pistons?

This forum is more for users that are advanced and not really for novice tuners. It's a good place to find answers and info but you won't find anyone teaching you the way. You're going to need to get the basics down. I suggest getting Greg Banish's Engine Management Advanced Tuning book and reading it till it all makes sense. Then watching YouTube to see how the interface and basics work (Rope Goat Garage is a good start). Then using your platforms forums tuning section and then coming here for more advanced tuning questions. Like stated you must at least have a WBO2 installed and logging in HPTuners before making any real changes. Getting your MAF tuned is essential.

Tell us you have the original file that you started with (the "as found") and I won't lose faith in you Lmao
Who did that tune? Many of the tables are out of wack and need smoothing. Never seen an IAT spark advance correction table add timing as the temp rises but I a new as well.
Don't let anyone discourage you. The salt here can get thick.
Oh please. Tuning isn't that hard (but it can be). You don't need a book or a college course. You don't need a wideband, either. That's a novice thing to say.
OP, start by verifying injector data then tune the VVE table. That's why you have problems on/off idle. Look that 'how to' up. You'll learn as you go.
guys yes 706 with flat tops AND no the pc i had everything on got stolen at a track so im here tryna just get a few pointers on how to make this pile of shit run to get to work lol its very under power i have fixed my 02s it was fuses and wide band will be about a week out if yall cant help then thanks anyways an it was a "friend" that said he knew how so idk
How old are you? Throw a period or a cap in there somewhere jeez.

Its not that hard and I taught myself without any books. I started with an SAFC through trial and error. The user is novice and why I said he should get a wbo2. If your seasoned and know what you are doing, you can make PE changes being pretty confident but I don't recommend that to someone just starting.

Nahh im gonna an sorry for nothing typing the way you like an im 26 an i work on heavy machinery so don’t have time to worry about how i type
How you type isn't for your benefit. It's for the benefit of those that you are asking for help.
You shouldn't be sorry, you should be embarrassed. You sound barely literate. And that's the nicest way I can put it. I struggled with that LOL

You don't need a narrowband or a computer either. Engines run just fine without modern electronics. When I started tuning widebands were not a thing yet and we made 122 adjustments to Holley carbs while inspecting spark plugs and 93 was $1.35/gallon.
It isn't what you need. Its what you can get affordably, simply and safely, which can make life easy and give you every edge to save time.
However. Widebands are dangerous tools to a novice. In car hobby level widebands lie constantly, vary with quality, pressure and temperature, position/installation, transient delay, an accuracy at fringes rife with insipid deviation. It will give an un-earned sense of security and potentially misleading conclusive from diagnostic pov if you are not aware of all the ways it can mislead and how to read not just the face value but also the behavior of numbers as they flick across the screen.
Like computer controllers, they are both potentially time saving and efficiency improving devices which can be reliably and affordably utilized and obtained, with potentially disastrous or crippling results for projects on any level.
Therefore IMO it isn't safe to assume usage for any of these devices and their potential use on the need, or not need, when it comes to engine controllers and tuning methods there are more important considerations such as familiarity and underlying working knowledge of engines which operate without said devices and those many microcontrollers as general devices which merely posses input and output integrated circuits on a wave front, amplification and interpretation platform, at such low voltages and currents as an engine utilizes in hobby installations and are quite simple compared to worldly higher electronics far from vehicles and future endeavors.
In other words wideband sensors, MAP sensors, IAT sensors, EGT sensors, etc... and ECU which interpret sensors are all on a similar level of electronic 'need' that is they are not needed at all and having them does not guarantee the data collected or will be utilized effectively or properly, and in trying to learn to use these devices to tune an engine should not be focused on just one or some of these but rather how they work on the whole and how to interpret data on the whole for any devices including ones never seen before or familiar with yet. I think one begets all, we should not limit ourselves or our potential based on our warped perceptions of need and not need solely due to familiarity and comfort zones for what is practical application in a general sense, it would seem to be advantageous to include as many sensors and potential tuning aids as one is comfortable with while at the same time becoming familiar with new ways to review and interpret data from both old and new styles of sensing equipment in order to keep growing, and not limit to any specific worldview of what is 'need' or 'not need' based solely on comfort and established canon materials.
Hell I'd say tuning is hard.
I can move through things pretty quick at my level but it came from being beat down by tons of cars.. "why won't this one idle" "WTF is this surge" etc
I'd also say that the fact a lot big shop's tunes look like total shit shows and a lot of tuners come and go also tells you doing a good job is hard.
I honestly don't know how new/young shops do it and not loose money on just about everything they do with too much time spent or comebacks.

I would agree with all of this. I'll leave it at that. I don't feel like bloviating right now. Maybe later.
