341.84hp 326.82tq. The car is stock, including air filter with a borla mufflers. By the time I drove into the shop and got on the dyno and ran my water temp was 220 already. The guy at the dyno said I he guessed I lost at least 10hp. The second run was even worse. He recommended next time to let the car cool off till 180 or so and I should have a lot better numbers. I just wanted a baseline better intake and headers. Should I dyno it again when the car is cooler or no?
