Sinister Performance, LLC. -- We're here
Just wanted to announce we've joined this forum.
Also wanted to make a BIG announcement that we've found aftermarket PCM tuning support for the 1996 cars! (We also have support for the 97 Bonne's and up thru 2005 model year). So if you were one of those "unlucky" 96 Bonne owners and couldn't find anyone to custom tune your PCM, your luck has changed.

Great guy right here. And VERY knowledgable.
I had multiple chips done from 2004-2006 on a real bastard setup. Customer service was unparalled.
He was also willing to answer my questions about tuning when I went off on my own.
Thanks Ryan!
