I have that blitz k1 turbo on mine it's not the power that seperate's it from the other ct9's it's the torque, it made the same torque ballpark figure as wepr's td04 hybrid on stock 4e and I reckon it's got more in it with some larger injectors slight more boost but for the same amount of money you can have the td04 set up which in the longer run is better especially if you plan on forged upgrade there is always going to be that bigger better option but the gearbox's become enemy's as you know haha I wish I had a nice little gt just to run 1 bar on a mine's ecu all who go big always come back!
