finally getting headers(arh 1 7/8) on and torque converter(circle d stall 3000 conveter) how long could i go with out a tune i should be able to get it tuned in a couple of weeks would that mess up anything if i babied it for those 2 weeks

 

i remember driving my yukon with a 3600 stall with no tune and the drivability sucked! i drove it for about 2 weeks and the converter is still ok 3 years and counting *knocks on wood* other then that i don't think it affects anything, ull get a CEL because of the headers + y pipe as well

 

well i know no horseing around until its tuned i just dont want damage

 

its gonna be tempting, just this one time common lol

 

yes i think its gonna be more fun
lol

 

I drove my 3000 stall for about a week while black bear was updating my tune, I drove it extremely mild and everything was fine.
as for the headers, you'll just get 3 codes, cat efficiency, and both rear o2 sensors (i'm guessing low voltage) haha

 

Well it's on got cel on but it sounds good there is more power just cant wait to get her tune then let the fun begin

 

right on man
I know its tough not to beat on it, but be patient for that tune haha!

 

My next step will be 80# injectors and a 102 throttle body

 

80# injectors are huge... what do you have planned? Way overkill unless youre going the boost route.

You drive a 6.2, right? newer one? That should be a flex fuel engine. Your stock injectors will handle everything you throw at it NA if you keep it a 6.2.

Why wouldnt you just wait to install everything until you can get the tune? That would be the best bet. The truck will run funny because of the rear o2 sensors.

who is doing your tune?


On another note... you must be pretty pumped. Your truck with those mods will be a rocket. You will run an easy low 13.
