Installed on my 18 l5p. Installation was pretty easy. It's not a 30 minute programmer install as they advertise. To simplify, remove the throttle body. This will give you access to the fuel pressure sensor. The intake system is good (similar to banks). The rubber insert for the turbo inlet didn't really bother me, so I used the factory resonator. Since then I have driven almost 300 km by car. It will take a few days for the transmission to learn the increased power. Now that he has a truck he feels very strong. Happy with the value for this setup. Its competition is around 300+ for slightly more horsepower.
