There was only 3 of us on Sunday to test them. We couldn't test all of them but the consensus that night was the b class tunes that I have made. They gave consistent lap times in testing. Under race conditions there was no superior car. Brog and Dog were on that night so I'd rather it be confirmed with them too rather than me making the final decision.
With the tunes they are limited to race tyres, aero for the heavier cars and small power increases to bring them all to the same spec. There can be no fine tuning within the tunes so no clear advantage from one tune to the next.
