Go for 740's - might as well get some proper ones

Why not increase fuel pressure to 4 or 4.5bar whilst you're looking out for some new injectors. That would make sure that even at 100% duty they wouldn't be leaning out on you so long as you leave the tune as is.

Walbro dont like working at over 5.3 bar pressure.

If ian is running 1.6 bar then 3.7 bar is the max I would go to.

Didn't he say he was running at 3.5bar?? Surely if he increases that by .5bar to 4bar it's well within the capabilities of the walbro??

Or did i read it wrong??

as i got my cat booked in for another map tweek, since my last one a couple of weeks ago, i was wondering if there was anything worth doing.

on the rr at clives, he said the fueling was spot on, but it stills comes up 100% on the injectors on the apexi connamder
