Little if no low end power.(most likely) Though the car probably feels like it just keeps going faster and faster and faster and faster and faster and SHIFT FASTER YET!!!!!!!!!!!!!!!

AND...
I have the graph too...although since it is in black and white it is hard to decipher. Perhaps someone with a little more experience reading these might be able to tell.

Thanks for the charts and graphs, Humanatek!
Those who speculated that this type of SC would not get us low end improvement were correct.
Up to 4200 rpms, stock has the advantage of a couple of HPs (5HP stock advantage max at 3600 rpms)
From there on, wow! Some samples
@4400 stock 98, SC 114
@4800 stock 108, SC 127
@5200 stock 119, SC 136
@5600 stock 132, SC 157
@6000 stock 147, SC 178
@6400 stock 166, SC 203
@6800 stock 177, SC 222
@7200 stock 187, SC 235
@7600 stock 198, SC 251
@8000 stock 202, SC 265
@8400 stock 205, SC 275
@8800 stock 199, SC 281
Didn't see stock torque figures on the chart.
Think about it boys! (and girls)

Not surprising, at 8800 rpms, when stock power is falling off, the SC is building at an even stronger rate. This looks like a cheek flapping, monkey smiling, Eticket rush!

And for those that want to visualise the above numbers
Rough analysis shows that if you do a 6K launch with SC you'll be generating about the same power as a 7k launch NA.
Torque figures would mean more though.

If HP at the wheel with the SC is 281, using the same formula as applied to Jim's dyno of 196hp at the rear wheel, this means the SC gives the Stook 344hp at the crank, 11hp more than the upcoming e46 M3.
For 5k, that is an impressive number. I would love to see 0-60 and 1/4 mile times as well. Quick, someone lend Jim a Gtech!
