Slower on spray I thought it was my low bottle doing it but I just got it filled 950 PSI, the AFR is dropping all the way to 10.5 and working down to 9 by time I cross the traps. Its flooding the engine with fuel badly. I only got 2 runs and then more oil on the track and left
NA on 100 shot
60 1.94 1.965
1/8 90.66 91.83
1/4 115.03 114.89
ET 12.396 12.391
Engine stock 346 with decent sized nitrous cam 229/237 on 114, LS6 intake, hooker LT and all the supporting suspension etc mods. TR6 plugs, I just pulled them out of the box and installed them. I have about 6 degrees of timing pulled across the board
Kit is a NOS wet plate kit, 100 shot. I had this exact same kit on my old 408TA and it was really nice, blew my trains up I removed it and put it on this car. I have the stock jets for 100 shot.
I checked both solinoids and they are both working(checked with nitrous un hooked but bottle on hard wired) I can feel it hit then drowned out.
Any ideas, blowing the spark out? Jetted wrong(went with what NOS recomends)? Season over but like to fix this bug before I yank the motor out and put a bigger one in.
Thanks
Jay

Also, those are the wrong plugs. The nitrous gurus all recommend BR7s

Wet kit I was thinking the same thing I have to check in the morning, I'll report back.
All the stuff I've read said TR6's its one step colder than a TR55?

Are you running an inline filter? I had the screen on my solenoid clog up with debris before. I kept upping the jet but had the same ET. Turned out the debris was the restriction not the jet.
BR7's are non projected. Guys say they are safer to run and it makes sense to me. I ran TR6's without issue but switched to BR7's.

Straight shot the only thing I have inline is the pressure gauge, maybe thats plugged, like the ideas give me some stuff to check and trouble shoot.

Jesus christ no wonder that thing is a dog.
Most normal 100 shot tunes are 52n/27f on 55psi.
Try that and report back.
For some larger tunes I would start with these jets:
150-62n/34f@55psi
200-73n/39f@55psi
250-82n/42f@55psi
300-99n/47f@55psi

Can some one tell me where I can find a good jet kit? All the ones I found are singles or you buy sets of 8.

I had a bad nitrous solenoid give me fits all season long. It would test fine, and then not work. I noticed you were testing it with the bottle unhooked. A bad solenoid could easily work fine without dealing with 800 psi of nitrous. Induction solutions also has great deals on their solenoids and offers a 10% discount of you mention yellow bullet forums. I'm not saying that your solenoid is the problem, it was just mine.

the jets were backwards, more rookie issues. I have the NOS system 408 with a fast 90/90 went in. I bought a 90 plate from nitrous outlet but my jets dont even fit inside the fitting there to big.
Can I only run nitrous outlet jets in there plate? Does the expected jets change now that I have much larger motor set up?
