Actually the reason they went to 60 lbs.of fuel pressure was that the bean counters got involved in the cost reduction of the package...the horsepower was pretty much already there and it was a lot cheaper to raise the fuel pressure than it was to purchase Millions of bigger injectors to give you the same fuel volume....while a finer fuel mist IS easier to ignite the volume of fuel you are trying to burn is the same because you haven't changed the amount of air ingested and you are working with a specific A/F ratio...any horsepower increase is minimal but when working on 1 engine instead of Millions the cost is easily justified when any increase in power is good.....
