My PDR works really well empty. My last dyno was 450/753 with a TST/Superchip and non-pop tested Jammer 3s. With my current setup I hope to be 490-500 cause the truck feels faster than before. When I run it hard the temps dont really go much above 1200.
BUT.... Once I start towing it gets pretty hot, but it might of been cause I was still running a COMP tune.
