I dont know what it gets for fuel economy i never bother to fill it up and check but it seems awesome. seems like ten bucks (about 3 gallons around here) will get me around for a week or so and i drive quite a bit. I know thats not very scientific but if i dont beat on it (which is rare) then it doesnt seem any different than it was stock. Last 0-60 was a little over 9 seconds on a stop watch, did 10 something on a video (its on here somewhere). Not rubbing it any, just kinda wanted everyone to know it didnt fail in a catastrophic fashin a couple weeks in.
