Hey guys im in the process of ordering my mail order tune... i have a couple questions (mods are in sig) i know for the cam i have it would benifit to have the rev limiter raised and when the cam was installed we also installed new 918 springs and retainers and also hardened pushrods.. my question is whats a save rev limiter with the cam... ive heard anywhere from 6400-6800 second question should i have the idel raised or leave it? i like the lope but i know that with this cam it can be tuned out... idk give me your opinions guys thanks in advance

 

Up to you really.
If you like lope go for it, else clear it off.
Also the less RPM the better for the engine. If you cam makes more power higher in the range you need to make a call.
More power and less engine life, or less power and more engine life.
6400 should be ok, after then you are accerating the wear which increases geometrically with engine speed.
