More boost
No more turbo flutter from stock waste gate. Much more boost.

Quality actuator
Excellent packaging and build quality. Both bench testing and on the truck held boost to 26psi before actuating the wastegate, allowing me to get the most out the AWESOME "RRDP ported housing billett compressor wheel" I installed at the same time. definitley a worthwhile purchase!

TURBOSMART PERFORMANCE WASTEGATE ACTUATOR 99.5-03
This turbosmart wastegate is smart for your turbo... towing a stock trailer showed increased power and mileage.

Wastegate upgrade
Fits nicely on stock turbo, good upgrade from the worn out stock wastegate. Truck builds and holds much more boost now. I don’t have a boost gauge so I don’t know the exact #s. Installation is way easier if your turbo is out. You could probably install while turbo is in the truck but getting the exact preload would be tricky.

great fit
Drop in replacement. Excellent quality. Went from almost 24lbs boost to over 31lbs with this and the KC turbine and compressor kit.

High quality
Don’t cheap out. Buy this one you won’t regret worth the extra money

Turbosmart
Wow! what a difference! If I don’t get used to the new acceleration soon I am going to jail.
Awesome addition! -
Wastegate actuator
Much quicker spool, less boost loss during shifts, more overall boost. Makes you realize how awful the stock unit is.
