Never really know unless I run it on a dyno, with a before and after reading .
The main thing is I'M a happy camper with the mods to date.
Like I wrote in another thread, I don't think it gives any more power, however, I believe it shifts the power band a bit to the left. I've been driving the mod over a year and I would estimate the power band is about 500rpm to the left on the lower side (up to about 4000rpm). IE, the torque you had at 4000 is now there at 3500, etc.
