Yup that sounds about right.
And as w8ye mentioned those limiters HAVE to come off...
The limiters would have been a great idea for a newbie if someone else tuned the engine first then put them on for the newbie...
But as they come from the factory they are rarely in the right range... Out of 6 Evolution engines, I've only found one set of limiters that had an acceptable range.
