Grimspeed Tuning Software?
you must be confused.
the grimmspeed is a modified mac valve 3 port boost controller solenoid that is controlled by the ecu. you program it what wgdc you want it to run etc in the ecu.. its not a standalone unit. it is plug and play on the evo 8/9/x , etc. but cant be just installed without a tune because the stock wgdc is set to 100% and that would result is lots of overboost.
