I am to the point where this thing is either going to get put on or its getting sold.. So with that said, can I put this on, drive the truck untill I get a retune, or is it a must as soon as it goes on?? Thanks for any info..

 

I drove my truck around for awhile before I retuned it seen a difference tho after putting it on and after a retune but ur truck is a little more modded then mine lol

 

Damn your slow.. I had a extra PCM for mine, that I sent off before the swap. Then went for a live tune later.

 

05gmcsierra drove his truck around for like 2 weeks with out a re-tune he hade no issues what so ever ...

 

I ran mine for a while with no problems what so ever, but a buddy did the swap and he had to retune it since it wasn't running to well.

 

John, it'll definitely run w/o tuning, I do think the trims will be off and for optimum efficiency and power a tune will be needed.

 

put it on. not necessary to retune. I added a slight amount of fuel, but wasn't anything to keep it from blowing up. Might not even need a retune..who knows.

 

Aight guys, just wanted to check, gona give it a shot tom maybe, but need not to be out a ride for a time

 

in order to fit this tbss intake or nbs truck intake besides the x link would i need a ls2 tb to make it fit on a 04?

 

I wouldn't get into the throttle without a re-tune once you put it on. If your tune is on the ragged edge with timing or fueling, it'll knock. Out of boost the fuel trims should take care of it, though.
