So do 155* spray angles.

Turns out I had 4x.011 injectors with the wrong spray pattern. Swapped in 5x.012 SAC Diesel Auto Power injectors and she's running alot better. Still not building boost properly. I'll be looking into boost leaks when the weather clears up and am looking for a larger turbo in the meantime. I know for a fact my turbo needs replaced asap.
Thank you all for your input.
Anyone have any suggestions on what would be a good match for the injectors I installed? I'm strongly considering an HE351CW. But if there's something that bolts right in I'm all ears.

I'm going the he351cw route soon as well, I snagged mine for $150. Just need to pick up a few odds and ends now.

There are quite a few options for actual drop in replacement turbos now days though. I'm on the fence now whether I should sell my 351 now that its all rebuilt and grab a drop in aftermarket turbo or just run it.

1997 ECLB - 5" Diamond Eye straight pipe - ISSpro Trans temp/EGT/Boost - AFC Live - boost elbow - 191s - Built trans - BHAF - ARP 425s - PSC SG852 - 315/75/16

Mine hits 5 psi like one second after pressing the accelerator and quickly hits 18 or so on normal acceleration. Might hit 30-35 with pedal to the floor if I'm pulling or going uphill. I'm passing 1300 rpm or so when the boost gauge zips past the 5psi mark. I get a puff of haze unless I'm just putting around gently. I'm not one to putt around though. I need to put a larger exhaust on, that will help I think. I've been considering the K27 turbo but my Holset is still in very good condition and I'm trying to restrain myself lol. I think I'm on the ragged edge of what the HX35 can handle right now though.

96 12 valve club cab lwb 2500 2wd 250k 3.55 gears, 265/75-r16, OFV at 30, no plate, AFC full fwd, HX35 at 35 psi boost, Timing~16.5, 5x11s, 2790 BHAF, Banks hi-flo muffler, 3.5" exhaust, Deleted prefilter & heater, mildly built 47re, billet single TC. KDPF
