I was an engineer at Chrysler for almost 10 years starting in the late 90's. We were forbidden from anything like DSE and to some extent Stielow are doing on any Chrysler products. One of my friends at Chrysler had a side business making suspension and stiffening components for Fox and SN95 Mustangs since he couldn't do anything for Mopars.

We weren't forbidden from developing and building stuff for our own rides, it was the selling and profiting that was frowned upon.

I have a 73 Duster with a JTEC 5.9L Magnum and Ram electrical architecture I have been working on for 12 years, and I know it wouldn't be where it is today if I couldn't have called some engineers for guidance and help (not to discount guys on here like AndyF and Dr. Diff).
