I found these over on a Dodge forum (my mom owns a Dakota) and figured it might be of some use here. Wasn't sure where to put it so I put it here since I have a 2nd gen ZR2. Do with it as you please, maybe it can be somewhat useful to someone.

 

I have a similar chart for the "Turbo Power" brand. I can get a pic if anyone wants it/would find it useful.
