I am running 1000cc injectors instead of 600-800cc which may be the issue. No other explanation for the fuel pressure being so high.

Some clarification and a non-update:

-The reason my fuel pressure is so high is because I'm trying to tune 93 octane on 1000cc injectors/340lph fuel pump. If I were to *only* run E85, I'd be fine but since I'm insisting on a backup pump gas tune (because knowing me, I will run out of gas at some point), we're having to install the return system.

-Hill's called yesterday and let me know that they now have the Synapse BPV with the correct bung. Assuming it'll be off to the welder today and on the dyno tomorrow/Fri.
(Isn't this fun???)

Painfully slow status update:

Got word yesterday that the new fuel system is in, the new BPV has been welded on and the car is almost dyno-ready.

Could the end be in sight? So much like Charlie Brown, I'm going to get excited to run and kick the football again...

then GTM pulls the football away and laughs? lol

Nah, not GTM anymore. I haven't spoken to anyone there in over a year.

i know but i couldnt resist the joke lol

dmhenderson's Nismo '12 GTM supercharged build thread where I freak out a lot
 

Someone remind me again why I didn't/don't need upgraded MAF sensors?

There was a very good reason but I can't remember what it was. Driving me crazy.

Home stretch!

My appointment is the 27th of October! Hopefully my tuning isn't as crazy as yours.

I went a little nuts. The 1000cc injectors and the huge fuel pump made things...complicated. I want long-term reliability which is hard to come by on a non-built FI converted motor.

If you're doing the plug and play GTM kit, it'll be cake.

What's the brand of 1000cc's you've and what is the duty cycle on those?

Injector Dynamics 1000cc injectors. Duty cycle 92.5% - recovery time less than 1 milisecond.
(they are hot sh*t)

Got the car back from Hill's. Pump gas tune is done and it was a bastard. Injectors, fuel pump and fuel return system are playing nice with the new map.

Going to take it back in a bit to finish the tune for the E85 conversion but she's home for now.

Hills asked me a while ago to badge one of my intakes. I f'ed up the first one they gave me so they added one while it was in the shop.
