That's why I left. Sometimes you gotta know when to take yourself out of a bad situation...... before it starts.
That statement is true...but I’m wondering why your truck was with that clown you call your friend so long and is just now supposedly getting it up and running? Also, I didn’t mention this for you to take offense! I just happened to have a sick sense of humor!!

If you don't check up on that tucker, he is going to give you a bandaid for the cost of a gold nugget.

Well....his priorities are messed up. That's why I had mentioned he's a lousy businessman. You take in a job--you do it! Not keep pushing it to the back burner. I'm still a customer. He didn't treat me like this all the other times--and he's dome alot of work on my rides. Oh well, now I know.
Yes. Understood

I'd like to think with age--comes wisdom. And to know when to pick your battles. At the time my priority was to just get the truck running and out of there.

Whats up Tony been a while since I've been on here. I see you've been up and down with your ride. I got Denali cluster from you way back! I remember the original 6.0 you had installed. A couple of things I would address from the previous build. Make sure you run bigger injectors. I remember you running stock injectors on that cammed 6.0. It ran good, but it still think it was too lean and needed bigger injectors. As for the new one it should say "6.0" on the front of the block and have flat top pistons if its an lq9. The builder should be able to provide pics of this. Is Blackbear still around? I still have my Autocal from when my truck was tuned. Go HP tuners if you ever plan to 4l80 it like i did. My truck still runs strong 5yrs later and your cam specs are similar to my Vinci cam so you shouldn't have a problem other than injectors. Its all in the tune. I would put an A/F gauge on it so you can see how its running at WOT so you dont blow it up. Hoping this builder gets his shit together as these trucks are like Legos and should take much to drop a motor in as long as he knows how to use a torque wrench.

Good to see you back @bottomline2000! How's that cluster treating you lol? It's been a damn soap opera for sure. I think it's finally coming to an end. I still have the stock injectors, but I'd like to maybe get a set of flex fuel injectors. Think that'll work? Any recommendations? I'm on a budget also. What are you using? Simple plug and play? I won't need to retune for the bigger injectors?
The last 6.0 went because of cam bearings. Luckily it wasn't fuel related. Thanks for any and all suggestions.

Haha, the cluster has treated me well. Always fun to max out a 120mph speedo lol.. im running 8.1l 44lb injectors. They are direct plug and play, but cost me about $400. They were flow matched so not the cheapest. Be careful as detonation can take out cam bearings not just lack of oil flow. Flex fuel injectors should be sufficient although you may need an adapter harness. The tune should be calibrated based in injectors. I would invest in a solid tuner to make sure all is well. I'm thinking about pulling the heads on mine and having Atomic retune it. I want HP tuners for whoever does it. My autocal is locked to Blackbear, but if you need one lmk if you go his direction. I don't see myself using it.

Thx for the offer. I actually bought an Autocal off the classifieds--got it, put it somewhere--now I can't find it
! Typical...I thought FF injectors would be a direct fit, that's why I mentioned them. The tuner had said something about the injectors being at 90 something percent duty cycle, but were sufficient enough for my mods. Tuner was a douche tho.I def didn't know detonation could take out cam bearings. Gotta start using at least 89 octane now. If this motor goes I'll burn this bisch!!
Damn man. If my injectors were hitting anything in the 90% duty cycle range, I think I’d need to upgrade them. Your tuner does sound like a douche.Thx for the offer. I actually bought an Autocal off the classifieds--got it, put it somewhere--now I can't find it

Do you know what the FF injectors size is? As compared with the 8.1L @ 44lb? What about stock 6.0? Any difference between LQ4 and LQ9?
Sorry for the hijack @Tony. [emoji16]
I think if they were around 90% duty cycle before, he should upgrade! [emoji16][emoji106]

cant say iver heard of KR causing cam bearing to fail. chip and kill your pistons, yes.
injector up grade needs to be adjusted in the tune for sure.
my ss was on stock injectors with a large blower cam, hitting like 85%, the procharger came with 60lb injectors iirc. but up graded none the less.
so if your not 90% or higher you can let them slide.
good injectors will cost you way more then your willing to spend. 400 is cheap really. ive seen em up to 800 and a grand.
that new engine you need to find out if the injectors are the same, or if he's, the mechanic ill use that term loosely is re using your old ones. not knowing how complete this new engine is.

90% DC is okay for an NA motor IMO My Tahoe is close to that and I'm not concerned. I would always recommend the higher octane if available but like I said before it will revert to the Low octane fuel table and pulling timing if it senses any knock. Unless the cockgobbler that tuned your truck just copied and pasted the high octane table over the low octane making them the same then it could be a problem.
I have heard knock will hurt cam bearings but back like I said before it should revert to the low table and pull spark if it senses knock. It will also add fuel if it's knocking due to a lean condition which will be identified by the O2 sensors and stored by the Long term fuel trims (LTFT) which then get remembered until you disconnect the battery for a long time.
Basically what I'm trying to say is I think it will be fine, but it never hurts to have someone look at the tune. If you find the EFI auto cal even without having to pay or use a credit I think you could data log and email it to someone to look over and let you know if something looks dangerous. Then decide if it's worth it to get a return.

Hopefully that doesn't sound like total rambling and maybe someone smarter will fact check me. I'm definitely new to the tooning thing but I quit reading war books before bed and have been reading ECUs for dummies
