I want to know how much faster will my car (E90 2011 DCT M3) be at the ½ mile if I go with a stage 1 SC (550HP). My car has the following performance mods:

Akrapovic Evolution Exhaust
Dinan underdrive pulley
AA Green filter
ESS Akra Evo tune V2

Dynoed (on 30K miles spark plugs) 377rwhp (STD)

At the ½ mile trapped at around 138-139mph (suboptimal traction at the starting line I might add, this will be addressed later)
I know there are many variables to consider but just wanted to have an idea of what trap speed to expect (if its possible through simulation) if I upgrade to a 550 kit.

Thanks in advance.
