Going to an Edelbrock twin 52mm throttle body netted us some rather impressive gains. Around town, the car felt much perkier, and throttle response was crisper. Because the TPS comes installed and ready to go, installation was quite easy. As a safety measure, we also installed a 255-lph in-tank pump. It's a direct replacement and helps prevent a lean-out condition as our engine continues to make more power.
