Just bought this car with Fore fuel setup, lingenfelter 2.55 upper, lower and btr3 cam. The car threw a lean code and wanted someone to check tune for me. I also have a log file.
Appreciate it!

Check for intake or exhaust leak pre-o2 sensor. At idle it either has a terrible leak causing the trims to stay at +20-25%, this will cause a lean code for sure. Or it was poorly tuned to cause this condition.
If no leaks are found, it's going to be tune related and you'll have to fix it. Verifying other data should be done too, like your injector data. Looks to have aftermarket injectors and if the fuel system is stock, the flow rate data would be wrong for that style fuel system.

If you don't post your tune and logs when you have questions you aren't helping yourself.
The car has a fore fuel system. I will check tomorrow.
thank you for your input.
We'll need more details on this "fore fuel system", as of now it doesn't mean anything to me.
I had to google who that was and from a few minutes of research they offer parts for fuel system. So it's not just a "fuel system", it could be dual or triple pump setups, lines, regulators and they even sell injectors. So knowing EXACTLY what parts are installed is what I was kinda looking for.
If it has a return system, great but does it really have 90lb/hr injectors compared to the stock 56lb/hr injectors??
If you can get that information to us, it may be pretty helpful in making sure the calibration is setup right.

Yes, it has 90lb injectors to run e85 tune. It has a dual pump setup with fuel return setup.
I checked for leaks and have none. So can someone point me in the right direction to adjust my tune? Suggestions?
if you smoke tested the system and found no leaks and youre sure all the data is correct for the fuel system id add 20% to the maf since your in maf only and see if your trims come down

The car threw a P1175 code, the car started loading up and quite on me. Can someone help a guy out on the tune?

I am going to add the 20% to maf.
I'd reset your LTFT's and log again. Your LTFT's don't come close to matching your STFT's. Take it easy until you figure out your fuel trims.

Do you have a Fuel Pressure gauge?
Make sure you really have proper fuel pressure before you mess with the tune

Not to be mean but how can we really help if you don't really know how to tune or work this software yet?
We could tell you exactly what to do until we are blue in the face or are fingers fall off but you still won't have a complete grasp on how everything works and you'll still be lost.
Jumping into this with a very modded car is probably the worst thing to try and learn on.

I appreciate the help and I do have a fuel gauge and will work on the trims. I will research and work on the tune. It is driveable but needs to be tuned prior to doing more spirited driving. I will work on the ltf and stf. The car had a new battery installed recently and has quick connections. The negative was loose and what caused the stall. I fixed battery connections and fired right up. Anyhow, I will seek out a dyno tuner and get car tuned. Appreciate the help.
Well, did some checking under the hood and found the aircleaner tube disconnected from the throttle body and one vacum line disconnected from the tube. I am going to drive car today and see how she does. I did check all my wiring and fuse to the Fore fuel controller and pumps. Thanks for all the help guys and I will post up some more log files.

Highlight what you want to change in the MAF table and then put 1.2 in the box and hit the "X". Or highlight the entire table if you want to add 20% to the whole thing.

Did you reset the Fuel Trims and log again? I would do that and then adjust the MAF table according to what your scans show.

Your STFT's don't look near as bad as your LTFT's.
