Injectors maxed at 10psi??

[sidewaystsi]

I took a log today, for some reason exel is sucking it right now and wont let me upload so ill just do this. Third gear from 2,000rpm to 6,500rpm. I notice at 6,031rpm the INJD is at 95.3%!?, timing is 22, 0 knock, o2 reads .74v. My mods are in my profile, but im only at 10psi of boost! Their stock injectors but they shouldnt be working that hard at just 10psi, they should be able to handle more that that, right? Anyone have any insite as to why their almost maxed out?

well if you are on stock turbo...it is wierd to have the IDC that high ...

but if you're on a big turbo, those stock injectors can get maxxed out quick

10 psi on 14b doesnt need as much fuel ..

GT35 turbo on 10 psi flows way more, thus needs more fuel...thus maxing your stock injectors...

You still on the 14b? If so try doing boost leak test. Make sure everything is tight and not leaking. If everything is good. When was the fuel filter changed? Might want to replace that.

From what mods you have in your profile I'd lean towards a huge boost leak! Do a test and get back to us.

Yea im still on the 14B and im sure it could use a fuel filter change. The only boost leak i got is from the throttle body shaft seals(big suprise) but its pretty small. Maybe the injectors themselves are clogged up? Also i notice the fuel pump voltage drops alot at WOT, need to do that rewire when its not so cold out. Would the pump losing power make the injectors work harder?

Did another boost leak test yesterday and found that the bov is leaking like the titanic. Must have just started right after the last boost leak test. Thats probably the cause of the high injd huh?

probably not if it wasn't the original problem
