Hum, I thought the rev cut on the cis 3 cars was in the ecu........

I was thinking of the effect on the valve train and the ability of the 
hydraulic lifters/valve springs to keep on the more aggresive cam profile...

according to the almighty Desktop Dyno most of the horsepower will come up 
from should fall in between 6000 and 7500, and my peak torque will be around

5k. Assuming that this is correct(and I take these kind of programs with a 
grain of salt) most of my power will be out the "useable range" except maybe

on the track. OF course the same program says i should be making about 203hp

at the flywheel...(155 at the wheels?) doesn't seem very likely. Of course 
that means I have to get the fuel sytem functioning properly to find out. 
lol

Besides that, is the over rev present in the standard cis e? It uses a 
different fuel pump relay, as opposed to the funky one with a slot for a 
fuse in it.
