the moral ethics and values in this thread are through the roof! haha. how much for the roller?

 

Also this might help me with this issue. I was tunning it to turn the cats on in the truck, since I took the converters off, and we turned off the AFM so it wouldn't drop cylinders. I don't know if this cause more harm then good. But I just want to figure out what my options are.

 

it would have to be 20 grand since that is still how much I owe on the truck
I made the mistake of signing a 5 year note enstead of a 3 year note like I was wanting to.

 

SDPC can hook you up with everything u need to do the dod delete for under $475, probably cheaper. hell ill send u a stock cam if u cover the shipping. There is tons of info on here to do it. I say do the dod delete, put in a stock cam and roll. Whats the oil psi like out of curiosity?

 

no your good on this...i turned dod off in my new 2013 w/ no problems

 

See that is the other thing. Oil preasure is perfect! stays the same under throttle and stays the same at idle.

 

Took it to a mechanic friend as well. We did new plugs, wire, injectors, and throttle body.
He said he wont mess with it anymore because that usually fixes a missfire, and my dad who knows more then I do said he has no idea. I'm just completly speechless on what to do with it.

 

if i were you, i would start with changing your oil and cutting open the filter and see if any metallic particles are in it. IF i remember correctly, GM had some issues with the older NNBS
lifters.

 

sounds like a lifter/cam issue. DOD delete, new cam/lifters and be done with it!!

 

yea i would surely take it apart and see whats goin on before you put a 4.8 in it and screw somebody over.

owing 20k on a 2009? is it a LTZ?
