    🎤🫳 ICYMI: @_dietsch_7 not only WON @ihradragracing 🎤🫳 ICYMI: @_dietsch_7 not only WON @ihradragracing Pro Stock at National Trail Raceway last weekend, he reset the national ET record. TWICE. ✌️
(and he did it with #BigStuffTPM 💪)

🗣️💬 Had to pedal it to set the front end down and get the win in the first IHRA triple crown race, to keep the fight alive for the million dollar bonus.
With the pedal we still reset the national ET record that we reset in the previous round. This car is flying.
