My engine is dipping rich very quick at high rpm from about 6400rpm onward. I am wondering if this could be effect of my 918 springs being worn out? They have been in along with 1.8 rockers with a 525 lift cam for about 35000miles. The car has done 99 11s passes and another 100 passes with the springs in.
