I ran across an old forum thread on GPF which blew my mind. I always figured a Lacrosse or Lucerne top swap without electrical wizardry was not a possibility.
As far as I know. I am the only one dumb enough to attempt this. So let me just let everyone know where I'm at. The Car... 2005 Buick Allure with 150k

I've always written these off thinking that there was no way to make them anything more than how they were sold and that's just too dang boring for me. However, a simple top swapped Lacrosse sounds like the perfect mix of fun, easy, and reliable to suit my daily driver needs.
So what does 3800pro know? Can I really just plug my HPTuners into a 3800 Lacrosse and tune it like any S3 Grand Prix?
