OK did a few WOT pulls today on the dyno and logged the pulls I was seeing 80-86% duty cycle up around 5800-6200 RPMs. This is a Stock TB with Stock Injectors and the AFR was not leaning out but my HP just flat lines (101/109) at that RPM. Am I at the point of needing larger Injectors and TB or is it the cam?..? Build specs are below in Sig. From what I can find searching it seams 80%+ Duty cycle is bad so what do the experts say??
