Wish I had bought a factory turbo
Not a fan of this turbo for towing. This is a good turbo to hot rod a truck but its terrible for towing, a least with mine. It has way too much lag and all the power is too high in the RPM range. My EGT's are out of control (1275-1350) when towing if I set the tune to have any reasonable response. If I set it for max EGT of ~1100 then the truck won't get out of its own way due to lag. I also cannot hold speed in high gear when towing. It either likes 50mph or 80 mph but nothing in between . My truck is lifted with stock gearing and 38" tires which certainly adds to the issue but the stock turbo worked just fine for me

Turbo
I bought this a little over a year ago now and its running strong. My only complaint is it is not polished like in the picture. Overall the best deal I could find and super fast shipping. Great product.
