I have about 15k on it now or close to it. Iv never run it on high boost in the 1/4 yet but Iv ran it in the street and it feels great. 1/8 mile run is around 7.4 and thats with about 21 psi. It seem like everytime I get ready to go something comes up or it rains. latly I have not made any good passes at the track and I dont have my et streets anymore. I got a 14 inch brake upgrade and now nothing fits decent..lol
