Only in that you've perhaps misinterpreted what I meant by gradually".dynamix wrote:Boost will start being wound up a little from around 500 and rev range extended. I have never believed in a strict 4000 rpm limit to 1000 miles then nail it. I have always run them in gradually, easing up the loads / revs as it wears in - i believe that it runs it all in more evenly.
Luckily Mike agrees with this and to be honest it will probably coincide with the progress with the mapping.
