well, there's the cam, the porting and polishing, a few thousandths off the
head, taking out the miles of convoluted intake piping and the highflow
exhaust, but realisticly i expect more like the 170-185 range, still pretty
good for 2.3l.
most of these programs calculate for a perfect world at peak performance. Of
couse if that were true all cars would be 500hp v8's and get 50mpg...

anyway,  can the rev limiter be bypassed? different relay maybe?
