on a stock fiero v6 4spd I went from 16.0 down to 14.4 with a 100 shot. On the L67 swap I went from 12.5 to 11.9 and gained 10mph in the 1/4 mile using the same kit and jets. Nitrous is fun but its addicting and get expensive filling the bottle all the time.
Whatever happend to FieroX's video from like six-seven years ago? It was a white '85 GT that didn't seem to blow up no matter what go thrown at it. I think he threw a few shots of nitrous at it and it actually took a bit for it to blow up.
Make sure you add a fuel cutoff switch. Remove the shrader valve and you can just connect there. The best is to use an electronic TPS switch. I got one from Dynotune. Oh and the most important is to get a bottle heater. Specially where you are. Not sure if that blanket heats too. Otherwise your shot will be like a 2hp one
You'll want to change out those worm clamps for hose clamps that are rated for fuel injection use. Otherwise you're risking a fuel leak. There are no "teeth" to cut and dig into the hose:

Unless I'm mistaken, those worm clamps are on a vacuum hose. He's using steel braided hose with AN fittings for the nitrous and fuel plumbing.
Without Nitrous: 113hp, 151tq With Nitrous: 155hp, 207tq
I was hoping for an increase of 40 - 50hp with nitrous, and we got it! I used a NOS brand bottle and solenoids and the NX Shark nozzle fogger.
Nitrous jets: Fuel: .020; Nitrous: .036 ..
What mods does the 3.4 has or was it just a stock swap? Those 56lbs of torque is what you really feel I ran 41 nitrous 20 fuel when I sprayed the 2.8. Your AFR looks on the safe side.

I wish it was a stock swap based on the low power readings... The engine is stock other than a "260" Comp Cams camshaft from the Fiero Store.
your 3.4 only had 113hp stock? That seems kinda low..
I am thinking that as well..
Considering the 2.8 was 140 stock (at the crank), and the stock 95 3.4 was 160 at the crank...
I understand with higher RPMs running out of breath due to the restrictive intake, but why are the initial numbers so low? Are you really losing that much horsepower through the drivetrain? Automatic transmission I assume?
Otherwise, very informative thread! Not putting anything down, just curious as to the low readings.
