Dynoing
#2
You will most likely have to car to a car shop that sells aftermarket parts and works on cars. It can be hard to find a shop with a dyno sometimes though. Costs I have seen are like $80 or so for 3 pulls. You can pay more and they will actually help you tune your car to pull as much HP out of it.
Note: Last year at NOPI, they were giving away FREE dynos for people that were on the SUPER STREET TOUR.
