wow really? I get 350 on a full tank..of cource I do my shifts mostly around 2500 rpm..and keep it at 2500 (give or take)...but I will get on it on the 1 mile away from my house... a downhill straightaway...fun wide curve to the left...then a steep downhill curve to the right, sharp left into my neighborhood, then another hard right and straight to my house..usually no cars there so I test the stock MP5 suspension lol
