Awesome product extremely more fun than stock and went in as easy,lined up perfectly. Best price I could find anywhere! Only thing I didn't like is the box was really banged up and a big heavy expensive turbo needs better care when shipped!

The product is great and the price is the best out there. The customer service from RiffRaff is excellent, I called left message and in a very timely manner returned my call. The call was quick and efficient and I was very happy.

Shipping was very fast and price was unbeatable. I got tired removing my stock turbo and cleaning it every 2 years to clear codes so I replaced it. This turbo whistles non stop and gets people looking. I lost about 8 psi of max boost, but it makes boost lower and faster, 20-21 psi max. Combined with my tune and bolt ons, this truck pulls hard.

This turbo seems a lot better than the stock one milage is good.Cheaper than Amazon.

Bought a 2005 F250 and figured there would be some repairs..But when I needed a turbo I searched and found this at RiffRaff. Price was great but their ability to overnight it to me AND answer questions about the install was beyond what I expected! I'm not only a customer for life, I'm and FAN! Thanks to Clay and the whole team at RiffRaff!

I'm happy with this purchase it arrives fast and it works awesome very happy with the whistle

I'm in love with my powermax turbo! Thank you very much for your honesty. This was shipped less then an hr after I ordered it. Was on my doorstep 2 days later in MN. I paid over $70 for shipping because I needed it quick & was still cheaper than all the places with free shipping! Thanks again & I look forward doing business with Riffraff again.

This is as much a review for Riff Raff as it is the turbo. I needed a new turbo stat and looked all over the internet once I had decided on a Powermax for my 05. Not sure why I didn't run across Riff Raff sooner but I almost bought from some place back east. Luckily they didn't have it in stock and wanted a week before they could send me one. Riff Raff had one to me in 2 days for $150 less. Impressive. I'll be using these guys in the future. The turbo itself was as advertised. Pretty easy to install, make sure you have a gasket and o-ring set which is not included. There's a slight power increase which has been noticeable even at take-off. The whistle is markedly louder, but I've got a 4" turbo-muffler 5" muffler-back with 6" tip exhaust. Not sure how different it would sound with stock exhaust. So far the best improvement is EGT's. +-100° decrease in EGt's under heavy load. Turbo boost pressure has also increased. I've got a max of 30psi on my Edge W/attitude programmer readout, a 3psi increase. This thing moves some air especially over stock. If you're wanting or needing to get a new turbo, but don't want to break the bank, get this turbo. If you want a performance turbo upgrade but don't want to blow your 6.0 to bits, get this turbo. If you've got more money than sense, if you need to compensate for your non-existent manhood or if daddy foots the bill for your truck habit, shop elsewhere.

Went in fairly easily seems to be running great so far Talk to customer service they were great I will definitely be buying again parts that I need for my diesel which I already have
