<<<The main problem with going to a non stock cam iswhen you have allot more
duration this disrupts the vacuum signal and youcan't have that with fuel
injection systems and still have driveabilty.>>>

It is not true...for me at least...

My modified engine with a bigger duration cam, ratio rockers, lightened
flywheel, mildly ported heads and the Aussie Chip can go  from @1500 rpm and
back to 5000+ rpm in fourth gear (@25 mph to @75 mph,  I have one more gear
to go also...)  smooth with no vibrations...
