Could you describe how the sensation of the car pulling evolves through the rev range, say in 2nd to redline? Since my sneaky leak was fixed, I am quite happy with the midrange pull (as you say, 3k+), but feel like the car is not pulling significantly harder after about 5k (this is the natural torque peak, but still). Do you spin the tires in 2nd gear on dry pavement?

Where was your leak found? Only one, or multiple? Any details about the equipment used to locate it?
i find the car drives really like a switch if on the sport button throttle map, i do love the little things though like ess has programmed a sport button memory ;-) so if you switch it on, its always on, whereas before it would turn off with a car shut of, if i accelerate full bore from 1-2nd, 1st is a good amount of wheel spin, enough to leave clear 11s in the roads, depending on the weather and coolness i get wheelspin in second or a "constant squealing" form they tyres as they JUST hang on.....

i did notice after half a day at the track i could no longer spin the tyres by midday, that was either because power was down or the tyres were creating more grip..... im suspecting alittle bit of both. The actual s/c unit get SO hot after a day of beating it was untouchable... i was however pleased to see this s/c unit can take absolutly anything the s54 can throw at it... The biggest issue with a centri blower?? that lack of Tq in the lower rev range.
