Short answer is... yes.. but you can get the same gains for free by simply advancing the base timing.
The EFI system in that vintage truck is very basic which is both a blessing and a curse, there aren't many plug-in tuning devices available and there isn't much for those devices to adjust, but since the motor still has a distributor changing the overall timing advance is easily accomplished with a timing light and a wrench. And because the EFI system is so simple it won't counteract thing you do to increase airflow through the motor, so installing a free flowing exhaust or 1.7 roller rockers will produce power gains.

Yeah that's right, 1.7 rockers will poke the valves open a little more(stock ratio is 1.6) which will increase airflow through the motor and make more power.
