I'm spraying 150 shot on my C5. Only mods are Vararam, Ported LS6 intake and corsa mufflers. I'm running the dynotune kit controlled by a NOS window switch. When running the car on nitrous it will pull fine, but then die after the run. After cranking for a bit it will start up and run just fine, no issues what so ever. ECU isn't saying that it has ever had a lean condition. I have my WOT switch set to open at 4.2v on the TPS and between 3100 to open and 5800 to close.

There are my plugs.




Any ideas? I have found a few things that say you need to slow down with the car in gear otherwise it floods out. Which would make sense because the car will restart and run fine...

car will have same AFR condtions as plug in your hand when you let off. In this case, a little rich. Car dying is not a big deal, just roll it in 4th and recrank.

Car dying isn't a big deal?

just re-read your post. I see you car is mostly stock. Yeah, I would not really expect it to flood out and not want to restart right away.

Are you spraying before the MAF?

That first plugs seems to have a little more spark/heat than the second which is not unusual for a plate, but overall the AFR looks rich to me. I think this is contributing to your situation.

I would like to see a little more heat in the cylinder by leaning it a little.
Based on the first plug, may wanna take 1 or 2 deg spark out before doing it.

I'm running a plate system. Stock timing. BR7EF's. I feel like car dying is bad!

Not my taste but looks well done.

there could be a big problem...I would start with pulling 4 degrees and then checking the plugs, and its probably going to want to go leaner

Stock timing? Stock Tune?

Make sure you have it jetted right and tune that ****.

Stock timing, stock tune. Made one pass on 150...car died and then started right up and ran fine, but didn't wanna spray again. Jets are as recommended .64 nitrous .38 fuel.

I'm going to guess this is in order?

A tune is in order. A wideband at the very least so you know what's going on. And you almost certainly need to pull some timing.

Probably just needs pistons lol. Serious note though, it needs a tune before you spray it again. Unless you want to put another short block in it. JMO

You need to get it tuned. Odds are its rich. You are playing with fire not knowing where you are tune wise.

I ran it once on 150, beat a bolt on new 5.0 mustang by walmart lengths, and never did it again! I have it on 75 now, and runs well. Putting a racetronix in it, finishing up the exhaust and getting it tuned.

Definitely needs timing pulled, very good odds its way rich with those jets.
