An MS3Pro PNP for Buick Grand Nationals
 

We've just released a plug and play ECU for the '84-'87 Buick Regal turbo models! We've reserved the first batch for our dealers instead of direct sales - contact your AMP EFI reseller if you'd like to get your hands on one.

This is a tunable race ECU that fits in the stock ECU location, plugs into the stock wiring, and uses all stock electronics, then lets you tune for whatever you throw at the motor. Features include boost by gear, traction control, onboard data logging, individual cylinder tuning, and more.
