Thanks.
I did approximately 20 min cooldown after runs 1 and 3 but <5 min after run 2 since it was just a repeat. My point was that if people are looking at the difference between runs 1 and 3 to evaluate intake gains (since run 2 was adapting) then some heatsoak may have occured since run 3 was smoother but torque, HP, and boost are also slightly lower than run 2.
Clearly the intake has a 10 HP and 10 ft-lb torque gain, possibly up to 20 on some parts of the curves, by comparing runs 1 and 2. Unfortunately Procede was adapting on run 2.
