Thread: I'm new but what do you use with your laptop to tune your grand prixs?

I have a 2003 GTP I want to tune use my Windows based lap top, I want free software I previously used HP Tuners on my 2002 coupe GTP. I want something I can tune using my laptop and OBD2-USB. Any suggestions?

your choices:

- tiny tuner (not 100% can be edited)
- DHP Powertuner (not free, and discontinued)
- HPTuners (also not free...)

Do you have a link I can use for Tiny Tuner, I downloaded PowrTuner earlier and It linked nice. How do you like Tiny Tuner?

never used any of them as there were enough people around me to me to not have to learn to tune.

tiny tuner: Tiny Tuner for DHP or HPT users

Greatly appreciated thank you, I've been learning the tuning from a buddy he went to college for it we tuned his DSM lol.

Tiny Tuner will not write PCM's, only edit.

If you want to write to a pcm, you need a used DHP powrtuner or HP Tuners. Powrtuner is typically in the $300 range and open for if not all 3800's after you buy the hardware. HP tuners is in the $500 plus range and you need to purchase credits.

That's about it.
