so i got my truck back friday night,and theres alot of clatter in the engine. it feels like it wants to turn off when im doing 55-70 at 1,100-1,500 RPMs.its starts clattering alot and jurking forwards. and im wondering id its because i have the 5.3 tune on it not a 6.0 tune on it.....and in the past two days i've wasted 3/4 of a tank and only gone like 180 miles......
Yeah youll need a tune

yea,i got a 6.0 swap froma 5.3.it runs nowhere i thought it was.or where it should IMO.the reason i havent got a re-tune is because the mechanic told me to wait alittle while to "get on it" and wait to get the truck tuned. and with my gf prom around the corner i've spent so much money on it,im broke now.and had to put the stock push rods on it.could that be a problem? it only clatters at 1,100-1,500 rpms. once i pick it up faster it sounds good anf runs good too
is it pinging?

pinging?nooooob here
ha
Clatter and ping are kinda the same in some circles. The reason you here it in that range is because that is the range where the engine has the most load under normal conditions. It's lean and the tune is off. Bad combo. Get it fixed.
Exactly what I was getting at. Get tune Asap
