They aren't extremely accurate machines. Even back to back dynos of the same car can be 5 to 10 horsepower apart.
Look, an Accord V6 made 15 horsepower:
According to this the Injen intake makes over 40 lb/ft of torque in the midrange on a Civic!
12 horsepower and over 20 lb/ft of torque throughout the midrange of the power band.
Look how much time passed between the stock run and the Injen run on the RSX... 
That must be a tricky install...
not trying to be a smartass but koreandude knows his stuff when it comes to engine tech but thats thats the only dyno we could find was a maufacutrers dyno.. the hyundai board we go to we've gotten dynos from peoples cars that they have gotten on their own.. if i drove the gt on a regular basis i could tell u if it made a difference. but since he had a 97 tib and all the mods he did made lil difference on the dyno and the track i beleive that the mods to this car actually made a difference. we are heading to the track tonight ill let you guys know how it goes..so far were working with 15.2 stock...
