you may get slight hesitation at low revs,i believe its best to get what you need and dont just go bigger cos you can. Ask your mapper he will give you the best advice.Ive ended up going down to 650's just to smooth things out a bit at lower revs.

Any opinions on denso,
i only ask because i just had new denso 720's in and they had slight hesitation problems if you accelerated quickly from basically tickover,Despite bob doing everything he could.Dont get me wrong it wasnt that bad but it could be better.Anyway the guy who sold me them (tlf performance) said send them back and he is sending me the 650's,if this doesnt help i will go for the power enterprize ones once i have the cash.

Denso's phase one injectors were fooking awful. Don't know if they've got better.
I had phase 2 740 Nismo injectors at 360bhp and they were superb. No hesitation no lumpiness and better fuel economy (off boost) than the stock 440's

the denso's a pretty good as top feed. Don't think Nismo make top feed but I could be wrong. Also I think Nismo are rebadged Denso's.. but then I just map cars with them on, I don't fit many.
