6.0 swap and problems
i thought this would be smooth as glass buttttt i can not get rid of these po171 and po174. i have checked for vac leaks with break cleaner put new intake gaskets new maf new o2s checked the maf wires for breaks and so far none of this has helped. my mods are vinci trucker cam, 799 heads, 4l80e 3200 stall, long tube headers. i have a nelson tune also. did the crank relearn too. the truck drives fine until i get on the gas hard and it boogs and is sluggish to go until i back off the throttle alittle

i told them it was a 5.3 to 6.0 swap. my fuel pressure is fine. well it is 55psi when im driving. is it hard to get the intake gaskets to seal. im stumped, if i unplug the maf the truck will fly

You try cleaning the maf if you have a K&N it could be oiled down. Or possibly they forgot to change the MAF tables. If it's intake gaskets you can leave the motor running and watch the fuel trims on the scanner and see if they go nuts when you hose down the intake with carb cleaner.
