Very impressive but what is eye opening is the 91 octane figure with meth injection. Horsepower rises to 358 at the wheels and torque to 310 pound-feet at the wheels for gains of 129 horsepower and 81 pound-feet of torque at the wheels. That is with the GIAC "Extreme" tuning file. Interestingly enough the 100 octane and meth injection figures mirror the 91 octane figures which has VWBoost a little confused. Either way, solid gains.
It seems the Loba Motorsport L0400 turbo upgrade may be something to look into for those who want something much more capable than the K04. The lag does not even seem to increase with this turbo according to the baseline dyno. Pictures and dyno graph below.
