So my main issue is a knock. It’s only when warm and don’t always do it. I’ve also noticed higher egts and a decent amount of black smoke which is supriseing for stock injectors? Also seems very gutless but that’s problably from stepping down in injector size. Can anyone suggest some remedy’s for my issues before I sell it and go buy another that runs right?

Sounds like a boost leak.

I just fixed a massive boost leak. Replaced intake manifold and plenum gaskets and all.

Prior to to all the smoke and high EGT's?

 

Is your boost gauge reading normal now?

Yes it was prior. I had way high egts and lots of smoke and they’re still is a little bit but not much. And. Can’t find anymore boost leaks. 

Did you use soapy water on all your boots? 

I actually made my own pressure tester, I'll have to find and take pics if you need ideas. Buy I could regulate psi in with engine off and listen, use soapy water and find any leaks. 

These trucks are pigs stock. No tuner correct? Didn't see it in your sig, just double checking.

No tuner right now. Seems like my truck don’t like tuners. Pigs as in slow or fast?

My biggest concern is that sometimes it runs good and smooth and sometimes it don’t. That’s what has me stumped. 

Pigs as in slow. While in stock trim it will pull a house but it is slow getting up to speed. 

 

 

Slow pig... What tuners have you ran on it?

You never gave the Quadzilla a true chance. Just expecting the "default tune" to work right out of the hole. Not the way it works. 

 

There will never be a canned tuner that will be perfect either. Being most of them are only designed for stock injectors. Like @dripley can say about +50 HP injectors and Edge Comp are smoky. 

 

Just running of the ECM stock tune is going to be pretty retarded in timing. Making it even slower.

Now that I have stock injectors I decided to give a used smarty a try. So far I’m pleased. No wiring no check engine light and feels like a lot more power although it’s no more than most canned tuners. I’m happy for now.
