Need a good 300(+)MPH tune for a Supra RZ 97

[Steve Causier]

I have looked all over for a good tune, but all i seem to find are drift tunes!
I know this car will do 300 + as I have been chased by one on many occasions!
I can only seem to get about 260 out of mine.........
Please help

You probably have to adjust your transmission, considering your car is most likely maxed out hp with nos. Once it tops off, only thing that really matters is your final gear ratio since your driving in a straight stretch road (don't know any track that you can reach 300 plus mph other than that one straight ring track forgot the name sorry). I am sure you probably knew this already, but might as well play with your transmission while waiting for a ideal answer you seek. Good luck.

How many threads do we need for the same question?

You want the 300mph thread, there's a link to a top speed Supra tune in there.
