Mach 1 - I got my Autologic chip from Johnson Motorsports (JMS). They're located in Irvington, Alabama. Website is
www.jmschip.com
I really wanted to get a custom dnyo tune, but didn't have the money for it. Plus, I had heard good things about these guys from people at my local track. I've got 3 programs on my chip that I can select b/t. When I spoke with the guys at JMS they wanted to know
everything about my 331. After a lenghty discussion they reprogrammed my chip from my old 302 setup and sent it back to me. Original chip cost was $300, and the re-burn fee a year later cost me $80.
The idle is perfect. I'm very happy with it.
So far, I've left the most conservative (ie. rich fuel, lower total timing, etc) program on just to be safe.
Hope this helps.
