its 11/6 at the moment but i'am having anthor map made up to run 11/1 for top speed runs.

11.6 isn't too bad, normally the top speeders aim for 10.5

yep i got it wrong, it was running 11/1 on the t3 at 23psi but with the t34 on 17psi it has leaned out to 11/6, so obviosley it flows a lot more air.
