Looking for turbo recommendations. I have a 07 6 speed 5.9 custom tuned with efi live. Mainly looking for a good reliable towing turbo. I have a stealth 64 on now and it does the job but wanting more towing power while being able to control egts a bit better. I tow anywhere from 5,000-15,000 lbs. Should I just throw a stock back in ? Any info would be appreciated. I do live at high elevation about 6000ft. Any info would be appreciated.
