is yours a multi port injection?
to my best understanding, excels are TBI?
fuel pressure is different with MPFI.
you are looking at 20 PSI (for TBI) and 40 PSI+/- (for MPFI)

i found this the other day, it should help you out.... i'm running the 4g61 injectors in my x2. not a HUGE difference, but i could tell there IS a difference.

ENGINE----INJ,COL----FLOW/MIN
4g15........yellow......180cc/min
4g37........white.......210cc/min
4g67........white.......210cc/min
4g61........orange......210cc/min
4g61T.......grey........390cc/min
4g63........black.......240cc/min
4g63T.......blue........450cc/min
4g63T.......yellow......510cc/min
4g64........green.......275cc/min
4g93........(((?))).....(((?)))
4g93T.......white.......390cc/min

the injectors listed above should be replaced with the maf sensor for better results
