275 mph supra tune

Hi,

a couple months ago i made a tune that has the 1998 Toyota Supra hit 275 mph on the motorway with the original 2jzgte engine. Does anyone know a tune that can make it go faster? I am trying to beat my friend in his modified McLaren Speedtail, as the Supra tune can beat a stock Speedtail.

Thanks.

How about building something that can go around corners? :confused:

fair enough, I’ll try that . thanks!
