I put our Corvette on the trailer (6000lb combined) and hooked it to Casper last night. I ran the full 670HP tune while towing. We drove for ~5 hours total from 1100' to 4300' up through the mountains, 1hr worth of bumper to bumper stop and go driving due to a closed freeway. 14.5 mpg includes track passes. EGT's max 1200 towing.
At the track the GT40R ran from 12.06 to 11.89 at 112. Baro was 27.01, 3600' DA. Very thin air. Boost dropped 3 PSI.
This backs up the 670hp claims. Nick D'Amico ran 11.95 at the same track and got 720hp with the same dyno with his LB7 CCSB truck. He used a ~220hp shot of nitrous, so his truck would not have been affected by the thin air. The Corvette ran about 6mph slower than normal, and 8mph slower than it's best. Casper ran 3 mph down from it's best.
Towing was very good, with very little smoke, and the charger would spool to 7 psi at 1500rpm when lugging it up steep grades. Need I say plenty of passing power?
Charger spooled on the line very easy. VERY EASY. Easier than a LB7 or LLY stocker. 2300rpm boosted launches and it didn't try and walk through the brakes.
All in all, I'm impressed at it's all-around performance.
