Thread: How to use DHP tuner?

I've never tuned the pcm on a car. I read the manual. What it doesn't tell me is how do I know what I should change and how much to change it? I've already got a DHP pcm but know that it needs to be "tuned better" since I put headers on the car. Any advice is appreciated.

The car will tell you whats going on, thus you'd make changes off of that.

But to know what the car is saying and what each change can do does take some knowledge and understanding of how the engine and various sensors work together.


Without me knowing what the car is doing, I can't really provide help.

There are some books that can give you a good start at tuning and understanding whats going on.

The car isn't doing anything wrong. I just want it to do better. Faster 0-60.

In my sig pic

I doubt anything can be changed to impove your 0-60.

Thats all about suspension and tires.

I guesstimate mid 5 sec. Definitely lost some when I put
the headers on

You lost some back pressure. It should still be able to break the tires free and .. spinning ain't winning. It's time to add some performance mods to the engine like rockers or a cam.
