If it is that reliable and easy to gain 90whp, I don't understand why everyone else hasn't done it (besides the whole "unreliability" and "voided warranty" issue is in the back of everyone's minds).

These are pretty typical numbers.
Guys, the problem with the high pressure fuel pumps isn't that they're being overloaded. It's a manufacturing defect that involves the seals. I'd be very surprised if the amount of fuel going through the pump (related to more HP) has any effect at all on the failure rate.
