I agree with Harold. I run GIAC stage 2 on my 1M and I've driven several tuned 135s with N54 and N55. None them feel as instantly responsive or put down nearly the same torque (as measured by my butt) as my 1M. I've dynoed my car and on a Mustang and I track it regularly. It's an excellent tune and I've never gone into 'limp mode' at the track unlike some of the piggyback guys I've met who are scratching their heads in the pits. Excellent post-sales support from them as well.
