detonating/misfiring/cutting out on 75 shot, help!! ok so i finally got everything all wired up for my tnt f1 wet kit, WOT sw, fpss, and ramchargers timing tuner. seems like everything is engaging wiring wise, but when it hits at the set rpm, it starts to hall azz but then is detonating or misfiring/cutting out every other cyclinder fire. fist set the timing on the timing tuner to 3 degs retard, and it backfired out the intake a bit. i reconnected the maf and lid that popped off, car is running fine, then i put timing at 5 degs, and it detonates like this, then set it to 7 deg and it seems a lil better but still does it bad. i dont know my base timing, it was tuned before the kit and had a steady 12.8:1 ratio. but im worried to retard it any more, could it be something else like the solenoids being bad or something?? i have the 18/31 jets in there for the 75 shot. dont know bottle pressure as my guage is broke so i have to get a new one but the nitrous is getting to the solenoid for sure(it was leaking at first). please help.

18 nitrous / 31 fuel ...in each nozzle? holy crap...sounds to me like it's rich as hell or you have typed it backwards...I hope. Best check how you have them installed. It should be 31 nitrous / 18 fuel for a 75 hit-o-juice.
EDIT: Yes, you can test with car OFF, key ON and disconnect your fuel line and turn off, disconnect your nitrous line. Stand near 'noids while someone else activates, you should hear clicking in each 'noid.

We have the timing tuner hooked up so how do we trick it to trip the noids? Can't we just splice into the power line and give it some juice for a second to test them?

It's your timing tuner, mine did the same thing. It's hit & miss, sometimes it worked & sometimes not. Ramchargers wouldn't admit a problem with it. I got my buddies used timing tuner & it works fine. Ramchargers will tell you that it's a problem with your CPS or you are getting interferance from your coils or plug wires. But they won't admit that you may have a bad TT. I'm getting away from the TT all together now. Don't want to trust my motor to that little box when I can just upload a nitrous tune with HPT.

yeah im pretty sure i put the jets in the right spots but ill have to double check that. yeah i want to test the noids but i couldnt think how to do it with the timing tuner, i guess i could just hook a positive and negative right up to it.
i do really think it is a timing issue, when we first hit it, it detonated real bad at 3 deg, almost like an explosion, i thought i blew the motor, thank god i just blew the lid and intake tubeing off. when we set it at 5 deg it was better and was just doing misfiring thing, it got a tad better with 7 deg. what im wondering is if i can go more on the timing like to 8 or 9 deg or something but im tuned, wouldnt my WOT timing be like 28deg or something? that would put me at 20deg timing which i doubt it good.
jamnut, thanks for your post. i would LOVE to run this without the timing tuner to see if thats the cause, but i have a manual car, and would be worried about not having a window switch or haveing no timing retard, plus i would have to rewire everything, i dont know what to do, i seriously hope my $270 timing tuner is not bad out of the box. whats the easiest way to test if it is bad?? so yours was doing the same thing? it would like start to pull like hell but like miss a beat every other fire.

When the RPM **** is at zero, you can test the unit with the engine not running. (key on though.) It will allow triggering for 1 sec when testing this way.
