I had a question about the ECU, and tech support picked up the phone right away. I spoke to a very friendly and helpful tech. It seems Spectre and K&N products are so similar they use the same tech support personnel. My question was about needing to have the ECU reprogrammed after install, which you do not. Make sure you don't skip disconnecting the battery for the duration of the installation. I was told that this clears the ECU, which then re-learns the data after you reconnect the battery and start the engine.
The video shows the installed intake. I have a Flowmaster 40 exhaust on the truck, and this Spectre intake. I definitely gained a few horsepower, and the sound is also improved, on top of what the Flowmaster already gave me. I can feel the difference in low end torque and acceleration. No engine codes or blinking lights after installation.
