08 gmc 5.3 turbo. 80lb injectors. Stock engine. Did the double stoich 1/2 IFR method

Hey guys, im having a problem with my tune. I had the truck running pretty good, just picking...

Sorry guys im an idiot and posted the wrong log file with that tune:doh:, was wondering why what you were saying wasnt making sense. Heres the proper log file for that tune were im picking up the kr...

Ok how are you guys fine tuneing your ve tables? I was told theres a way to use a histogram and copy and paste it to the main ve table using the paste special function but it didnt seem to work when...

Hey guys im a super new to tuning and have been tuning my 2008 gmc sierra 5.3l lc9 with a 76/75mm turbo deka 80lbs injectors and e38 ecu with 2.0bar speed density os, other than that engine is stock....

I just installed some long tube headers (cat delete) and the sensor wiring on car was too short to connect. But the location of the orginal rear o2 was perfect match. So i swapped the pins in ecm...

I will give it a whirl today, but I think I am running out of time. The snow has started to come down, so I wont be able to do drive aggressively.... But I will let you know how it goes. Thanks...

I did see the PE coming on last night so I changed the TP command to 45%. As for fuel trims, I have noticed that for awhile since I have been trying to tune this. That was one of the reasons I...

sorry could only post 5 attachments. So here is my drive, I see it happen around frame 1350

Is there anything obvious I am missing? Thanks again!

OK, lets try this again. First my VE stuff with new injector data
477414774247743

Then my MAF tune
4774447745

Got it working pretty good, started to look at PE. It goes rich about 12.5:1. ...

I will log again tonight after work. But the reason I have less PE is when I was going WOT my wideband maxes out to 10:1 and the truck is low on power, sometimes even will miss. I have larger...

So the last two days I have driven and driven.... The truck runs fine until I turn the MAF back on, even after I followed the steps to first tune the VE and then tune the MAF table. AFR is ok until...

I believe that spike in the MAF was because that was where my rev limiter kicked in and the rest of the curve was oe data. I have since figured out how to increase my rev limiter. So I will redo it...

I had turned the idle speed back down to 850 after I had driven it a bit and realized I didn't need it set so high. The truck was feeling good and I thought I could activate fuel trims and PE and be...

To start I read because of the larger cam I needed to set idle up. So I turned idle to 950 and logged several warm ups. Then I read to do the MAF learn. I did a pass at that to learn it. But then...

So whatever I just did was a HUGE fail. Here is the tune to show you.

47671
I thought I saved some scan data but I guess I didn't. Anyway at idle and low speed up to about 30 mph it is super...

The things I remember turning off are, fuel trims, cot, MAF (did something with the Hz) and changed a bunch of the torque management stuff

Hello, so I am new, sorry. So I have my VE table and idle and MAF all tuned. But in the hours of reading and experimenting I have turned off lots of things and am wondering what all should be...

OK so tonight I took it out and did a recording 4758347584

But I noticed for some reason my wide band was out 1/2 a point, so I adjusted it and made another pass 47585

My messed up "tune" is...

Just at work right now, but I will get the info later tonight. The vehicle is a 06 GMC 6.0l, 4x4. I installed a comp cam XR275HR-12, FAST 33lbs/hr LS2 injectors (because he has had several injectors...

when I click my own attachment it says "unable to parse log" so I am not sure if it will work for you

Ok I think I have the attachment here (my first attempt on any forum)

Newbe here, I am having a tough time trying to get this VE table down. My brain is hurting from reading so much!
