2003 GMC LQ4

Hello Everyone.

I have a 2003 GMC LQ4 that I want to tune for towing beyond what GMC provides.

Any thoughts?

Maybe set the Power Enrichment delay to ZERO seconds.
Maybe set the fuel parameters for E10 fuel, if using fuel with 10% alcohol.
Maybe "Tweak" the Abuse Mode parameters. (Sometimes it's better to allow the driver to be the Abuse Mode Manager?) :thumbsup:
Maybe "Tweak" the transmission shift points with "Bluecat" https://forum.hptuners.com/showthrea...Table-Software
Maybe convert to Electric Radiator Fans that will be controlled by the PCM?

Wow, thank you for the fast response and your time!

Can't access the link Bluecat supplied in the post, but will keep trying. I need to get hptuners software and play with it.

Happy New Year.

The software is an executable file, that works without HP Tuners.

Some skills with Microsoft Excel will be very useful too.
