maybe the aggressive timing maps in the lower rpm's make it neccessary to up the fuel pressure at higher rpms??

although i took the cheaper route, (s-afc) i don't seem to be having any problems. only took 4 pulls to tune it too, and the last two were almost a perfect single line. very consistant.

"Mine was perfect as well...till run 19. So it takes a while. I belive your car would do it as well if you ran it long enough, You should change your pump, you never know. At the very least get a fuel pressure guage (I think they cost more than the pump though!)"
i guess some day i'll need a bigger pump anyway. once i get more research done on better mods, more power, safe power that kind of thing. i already have a couple of fuel pressure gauges, maybe i'll throw one on and go drive it hard, maybe second creek or something, and see how the fuel pressure is effected. good reason to go to the track, right?
