Guys, I believe OP has N55 not N54 engine, all mods so far produce far less increase in HP/Torque. Cobb only promise 11% and 18% HP and torque respectively; gone the day of 50HP+ gain ala in N54 with a single tune. N55 proves to be more resistant to tune.
I'll say wait until someone crack the gate open.
