Alright, it's been a few days. Thought I'd give an update.
It didn't feel like all that much of an improvement initially, but after a few hundred k's, I�m pretty damn impressed!
The torque is amazing. just a hint of throttle really gets ya moving.
The most impressive thing is the top end. From about 120 (4500RPM) on up it really pulls hard and slams into the speed limiter.
All this on an untuned ecu, and stock exhaust. I can only imagine what i'm in for.
