bigred2005

I have a 2005 with 364,000 miles and counting. The waste gate on the turbo is seized so I constantly get over boost code when towing or working truck hard. I am considering upgrading the turbo a little bit when replacing and was wondering what the best turbo would be for towing. I tow a 15,000 lb toy hauler and 10000 lb skid steer often. The truck is also used to plow with. Truck is all original and stock including the transmission. The only modifications were to replace stock parts as they went bad/ got old such as a cold air intake and 4 inch exhaust system. Not looking to be some hot rod kid racing around blowing smoke everywhere and would like the truck to last another 300,000 miles. I simply want a better turbo for towing which still drives well on a daily basis unloaded. I am considering the aurora 3000 or the stealth 64. Any input would be helpful.
Thanks
