yeah i heard they were a tad under... you have any idea how much? The tuner there said they estimate a 17% drop from crank hp to wheel hp measured with the mustang..however, after looking around a little i've seen a lot of people saying there is a 10-15% difference alone between the mustang and dynojet... i'm in college so i'm not all that concerned completely with what the hp numbers are so much as how those number compare to what it should be making based on the small mods i've done to give me an idea of how healthy the engine is after 125k miles
