I'm running about 40PSI in the front tires to help keep rims safer in Manhattan.
The "High tire pressure" warning is continuous.
Can I change these values using a tech 2 or what would I need?

Any decent tuning software I could get to begin tuning myself?

I'm pretty sure I can understand a learn as well as make slight adjustments for small mods etc.

I have no experience with tuning computer controlled vehicles yet....plenty old school jetting, timing etc.

You can try one of these devices if you aren't running runflats:

It's unwise to drive on runflats without tpms sensors because its possible you wouldn't know if you had a flat. If you are running normal tires that box will get rid of your tpms system, or you can just run without them all together and deal with the tpms light for free.

Hp tuners and EFI live are the most common in what I'd call "real" tuner packages. It's direct access to a ton of tables and there's def a learning curve. Greg banish has some good books and DVDs that are good for getting started

Neither can do anything to the tpms system though, totally different computer that they don't have access to

You'll need a wideband also, if you don't already have one.

Tech2 is not able to adjust for TMPS differences.

Thanks for the replies. I have one more trip to my tuner this week for a pulley and tune then will begin doing this myself.
Wideband 02 sensor is a must I agree.
Just to clarify I am trying to change the point at which the message center posts warning about high tire pressure. Now is at about 40 or 41 psi. Id like to bring up to 45 about. Thnx
