A. Removing the rev limiter is DUMB DUMB DUMB if you don't upgrade the valve springs... there is a reason the rev limit is there...

B. Raising the fuel pressure isn't really neccisary on a cam'd car... generally they do not add THAT much more air... and beyond that the ECU will compensate with more fuel once the o2 starts reading it's running quasi-lean... and if you up the pressure the ecu will just reduce the injector event once it starts reading rich.

I had camS in my 1.6 sentra... bullfrog (they were great I don't care that they were regrinds... they lasted over 60k on my last car till it got totalled (Oh and hondamaniac... they were EXPENSIVE... a set for my old car was 900 bucks with core charge of 3-4 hundred (returned 8 MONTHS later (I sent the cams back the next week))) I was more than happy with the increase...

Also... not every aftermarket cam is going to give you more gains beyond the revlimit... many start to loose power...

Without the springs/retainers I would NOT suggest getting either the strip cam or removing the rev-limiter...

I had the street/strip gude cam and it made a good amount of increase... I never dynoed it but that car RIPPED after I had the cams in it... Also another thing to consider is your idle... with a strip cam it's going to be HELL... lumpy and loud as a mofo... people will ask you if you have a diesel... So if it's a daily driver... again I'd steer clear of the strip cam.
