At 91mph, rpm was about 2600 to 2700 rpm and 5.0 usec injector pulsewidth on flat ground. On my engine, VTEC kicks in at 2500 rpm, but this has no effect on lean burn, which is maintained up to injector pulsewidths of 6.1 usec at temps of 80F and up to 6.4 usec at 25F. I suspect lean burn will be maintained at speeds up to close to 100mph
