Help with my nt eclipse

[dn420a]

I have a 420a with hahn stage 3 with 330cc injectors, SAFC
and manual boost controller

My car keeps leaning out around 5psi
I have rising rate fuel regulator Ive messed with the SAFC and regulator and it doesnt matter it still leans out.

I dont know what is wrong

Can someone help

Thanks

are you still using the stock fuel pump?

By messing with the FPR, what pressures are you getting on that rail? And yeah, what fuel pump you running?

Thanks for responding,

I'm still using new stock pump and also external pump from hahn.

 

[dn420a]

I am getting 50 - 60 psi then when I'm pulling it drops to 20-30
In my hahn book it says to set it at idle to 50-60 then when boosting it should read 90-100psi

Once I give some throttle, pressure starts rising then falls off

I hooked it up to one of those OBDII computers and it said too much fuel so it is telling
ECU -25 whatever that means

Now tell me... you do have a missing link or voltage clamp on the MAP, right? Right? I'm no turbo 420a expert (yet), but it sounds to me like you've got something screwey going on with your FPR. I just think it's important to know if you've isolated the MAP from seeing boost. Probably have, but who knows. Do you hear the inline prime at start up?
