I just wanted to let all the Northstar Bonneville people know that, our cars can be tuned now. I just installed my tuned pcm from Madtuner.com today and wow what a difference in every way. He only did a mild tune because he hasn't tested it on a local car on the dyno yet to see how far the tune can go. All I know is that I'm at 5000ft altitude in Reno NV and the mild tune that he did for me made my car come alive in the thin air. I'm heading to the track tomorrow to make a few runs to see what I put down.

When you call or email Madtuner you will reach Ion, he realy knows his stuff and is a great guy to deal with. And I would like to say thanks to Ion for doing this for the small group of the Northstar Bonneville family.

I can't wait for the MAX TUNE!!!!!!!!

Any idea what software he'* using?

From the looks of the site, older cars he uses Tunercat, and possibly EfiLive for the newer makes. He appears to be a reseller of EFILive also.

If there are any tuners in the st louis area im very interested.

I only know of 3 or 4 people here on the forum that has a tuner. I have one, but I'm in NY. Sorry bud.

Hey Jaun, make sure they are not locking your tune. If they are and the company belly'* up, your out of luck.

Any idea of what the tune consisted of? What did they change?

I'll have to check at HPT to see if they opened up the GXP to their software.

I didn't see anything relating to the GXP on the supported list. Dan, HPT updated the Beta software just a few days ago? Probably in your login page at HPT.
