So you've added a programmer, 4" exhaust, and a cold air intake, but you're still not getting the power you were after. More than likely, you're not getting sufficient airflow. The factory GTP38 turbos are a decent turbo, but are pushed to their limits even with mild upgrades.

The Super GTP38 Turbo for your SuperDuty is a direct replacement of your factory turbo, but with MAJOR benefits. Featuring a larger, 88mm compressor wheel and 1.0 A/R exhaust housing, this turbo will drastically outperform the factory turbo, and is even a great complement to mild engine upgrades.

We offer the Super GTP38 in both a high flow cast compressor wheel, as well as a light weight billet. The advantage to the billet is it will spool noticeably faster in comparison to the cast due to its lower rotating mass. The turbo kit comes complete with turbo assembly and silicon compressor cover adapter (due to the larger inlet compared to stock).

You have the option of transferring this turbo to your factory EBV pedestal, unless you've already upgraded, or we offer a non-EBV valve from the drop down menu that will eliminate the troublesome EBV assembly from the pedestal. Furthermore, you can either switch your EBV outflow valve (on backside of turbo), or we recommend upgrading to the non-EBV version to eliminate the butterfly valve. While you can do one of these upgrades without the other, we do not recommend it. For instance, you can upgrade to a non-EBV pedestal, but then you will have to modify the stock outflow valve. By purchasing both pieces, you will be able to merely bolt the entire assembly together without modification.

This is a new turbo, thus requiring NO CORE CHARGE OR RETURN OF YOUR CORE!
