Re: Jeffm chip for 90 TGP You should check out the forums on W-body.com. That's where most of the TGP guys hang out. I used to have two black '89s, and I even converted one to manual using a getrag 284. Anyways, forget the Jeff M. chip and get one from Kenny at KAZ motorsports. The info is in the TGP section of W-body.com. |
