Hows it going? Quick question: I took a TPI from an '85 camaro, Took out the MAF sensor and converted it to a MAP sensor, changed the wiring harness to a '90-92 Z28, and am exempt from emissions, I have a brand new GM goodwrench 350 with stock equipment and was wondering what my timing should be. I'm not sure since I converted to the MAP and that I am exempt form emissions. Thanks for your time, I love my:hail: TPI unit!-

The same 6 deg BTDC was used on the map cars as on the maf. And thats what the stock chip will be programmed for in base timing.
