Fuel problem wideband logging ptoblem

[swappedturboej6]

Im having a few problems as of late with my car...

first wideband recording will only read up to 12.50 no richer, have the values set same as i found here on this forum.. i try and add more fuel even the slightest bit makes it run like shit. and the car spits and pops and will not rev past 7500 RPM.i take fuel away and it is not happy AT ALL but i can get it to rev higher.

ive seen duty cycles up to 85% at 15 psi!!???

i was thinking my injectors may be clogged so there at the shop,i have not seen the flow sheets yet and im not sure if they even tested them before hand. the car is in pieces right now.so i wont be able to try anything for about a week.

its a built gsr engine with a decent size turbo. lc1 walbrow 255hp and rc 1000 cc injectors gm 3bar its gotten alot slower. alot

but take a look at my cal and logs please.

You need to look at your fuel pressure...if it is dropping off then your pump is not able to supply enough fuel.
