How much HP does a 2004 Pontiac GTO really have?

Yeah, @benjamin84! If it gets clogged, you might lose horsepower. If you’re experiencing sluggish performance, it’s worth having it checked out.

Also, keeping your engine clean is essential! A dirty engine can lead to overheating and reduces performance. I like to wash mine a couple of times a year.

I’ve actually never thought about washing the engine. How do you do it safely?

Just use a degreaser and a gentle spray of water. Avoid direct sprays on electrical components. It’s a bit of work, but worth it for performance.

Agreed! And don’t forget to regularly check for any engine codes. It’s an easy way to preemptively troubleshoot potential issues.

I’ve noticed that sometimes adding a performance tune can also help bring out more HP and efficiency. Has anyone done this?

I had a buddy who tuned his GTO, and it made a difference! Just be sure to use a reliable tuner.
