Great hp&tq gains with a tuner bar none!
Love the sound, but hate the lag. Seems to give better hp @ tq. But the lag in spooling up is the reason for the average review. A tune or a more open exhaust would probably give me what I expected but not able to justify the added experience.
Nice performance upgrade that bolts in like a stock turbo, cant beat the price!
Riffraff is the only way to go
Easy install, sounds great even with stock exhaust- I cant wait to get my 4" full flowing exhaust on this week!
Great powerful product, got the sound and power I was looking for, great product... thanks fellas
great product quick shipping
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.
