Ok i just want to make sure this is most likely my spark plug gap.
Im running a dual nozzle 200 shot. 52 N and 27 F for the jets. I pull out 4* of timming on my msd timing controller and bottle presure at 900. It pops when i spray. " pop, pop, pop, " several times. I totally forgot to gap my Tr6's to .025, instead i left them at the factory settings. I was told to gap them at .025-.028 from one of the cold fusion guys. Or should i just gap them to .030 - .032 and work from there?
Please get back with me ASAP!
Thanks

pull MORE TIMING pull like 10 degrees...4 is prolly not enough...what tuen do you have? a motor tune or nitrous? i dont hav a jet chart but assuming your pressure is good then its prolly timing...
mine poped out of the exhaust 2 times...once with too much fuel and another with too low pressure on the bottle

Well i actually did run it 1st with 6* pulled along with 650psi. Its kinda cold here so it took forever to build up psi. It popped alot. so i waited and then pulled 4* of timming and let it get up to 850 and then popping actually was not as bad as the 6*. Maybe actually let it hit 900-1000psi and try 4*?
The car is tuned with 0* of timming all across the board. My msd timing controller is suppose to be on 15* which is equal to 0* on my PCM. So pulling 4* would be -4* of timing. Plus i have a LT1 355 forged, not a LS1

My car did the same when I had too much fuel and also when I did not have the right gap on the plugs. I have a 95 TA with a wet kit. I have my gap set at .035 with ngk tr6's and now it is perfect. Go you have a wide band? I woulsd also check air-fuel to be safe.

well the motor is forged. So id prob be popping headgaskets.
So what you are saying dave is pull out 15* of timing. Thats all i can pull out of hte MSD timing controller. I thought it was 4* since it is a LT1 OBD1 and all my timing is 0* out on the lt1 edit.
