The Edelbrock 90mm Pro-Flo XT single-bore throttle body is intended for Pro-Flo XT and Victor elbow applications and accommodates LS1 or LS2 bolt patterns. It uses LS1-style TPS and IAC and adds an idle bleed screw for improved idle control, allowing tuners to set base idle airflow independently of throttle opening for cleaner TPS signals and more stable idle behavior.
