Best stock replacement upgrade turbo available!!
This turbo with the SCTx4 programmer is the best additions I've done to my 6.0 Powerstroke for power upgrades yet hands down!!

Love the Whistle
Really woke the truck up. The stock turbo went out and after several conversations with Clay went with his recommendation on the PowerMax.
Glad I did not go back with the stock turbo
As always RiffRaff is the BEST PLACE to get Ford diesel stuff -
Great Turbo, unbelievable price
Love the way this turbo cleans up my tuned 05 and it was almost $200 cheaper than I could find anywhere else. I will be back for sure when I get injectors.

Stock 6.0 turbo upgrade.
Turbo arrived on time. Installed with no problems. Dont feel much power gains, but the whistle is much louder than stock.

Stock turbo swap with stage one swap out.
Easy to do at home. Helps if a buddy gives you a hand.

Best stock 6.0 turbo swap.
This turbo was an easy job anyone can do at home. Be sure to have a set of O rings and the oil feed tube gasket. My turbo did not include these, standard hand tool required, took 30 minutes to complete.

Stage 1 turbo wayyy better than stock and very noticeable difference
I was getting my 6 liter bullet-proofed and found out my Turbo is going out so I looked around online and found riffraff. The owner I was very polite very helpful and got my order to me in 2 days. The turbo itself makes a huge difference in the 6 liter it has a nice whistle that's almost annoying but you can hardly hear it in the cab in the power is just like a different motor one sided with the S CT X4. If I had to do it all again I would still order this stage one turbo it's fantastic and for only $1,067 you can't beat the price versus a $780 stock Turbo. Riffraff Auto Parts in Oregon has a website and they specialize in Ford motors I will just be shopping there for all my needs in the future

Shes a different beast now and loves to scream if i was 20 years younger might
cured what ills you. Had bad case of the turbo fart loss of power and just suck. stuck vains cleaned work for little while. Price for the upgraded garrett power max was what they wanted about the same for use stock rebuilds and wanted the core. Have youtube vid to show step by step, takes about an hour for r&r second time around..Glad I found the upgrade turbo they offer it made a big different CONS Cant keep me foot out of it.
