Holley Super Sniper Stealth 4150 Self-Tuning Kit With Gold Finish.

The Super Sniper Stealth 4150 ECU is capable of complete ignition timing control, fuel self-learning, improving idle stability, drivability, and wide-open throttle horsepower! The Stealth 4150 also includes transmission kick down provisions for GM TH350/400, 200R4/700R4 and Ford C4/C6 applications.
