There are a lot of factors to take into account when getting a dyno: the dyno itself, weather, gas (type/make), tire traction, ECU accustom to the mods, and extra. I think you will be in the range of my beginning & end whp/torque on the Mustang Dyno possibly. At the end of the day are you satisfied with what was done and can you tell a difference after the fact. I notice that you did not mention this nor did anyone ask this, but you have a tune/or going to get a tune?
