Recently tried to install 70mm t-body on my 89 automatic supcupe and check engine light came on with a code 63 which is TPS signal voltage is too low.Replaced TPS with a known good sensor and code was still there.Checked for correct voltage,havet.I replaced with factory t-body and check engine light went out.Vehicle runs strong and pulls hard with 70mm t-body on,just set light.Also she idled fine.Any help would be apprecieated before I sell.
 
I don't know much at all about the tps, but did you remove the neg cable on your battery to reset the computer after the install.

Just a thought. Others will be able to help you.
