I posted this on the nitrous section...see if you truck guys can help...here is the link. https://ls1tech.com/forums/showthrea...63#post1616763

 

are you detonating? was the spark plug melted the 2nd time you switched plugs?

 

What octane fuel do you use when spraying. Its definately detonation. But it may be from too much timing (atap it)...a fule issue (check your fuel pressure)..or an octane issue. If you use 87 or 89 octane put some 93 in it and try again.

Better yet...autotap on a dyno with a wideband if possible.

 

Sounds like it is not getting enought fuel to me!!. do u have an upgraded fuel system ? If not you should think about larger injectors and fuel rails. Switching to a wet kit could also help.

 

yea, might wanna get some injectors, retard timing.. or just get a wet kit.

 

Is it popping off your intake tube then it cannot read the maf anymore? Is the nozzle pointed straight at the manifold? You are running 91oct at least right?

Switch to a wet shot. It is safer and trust me will give you a ton more torque to the wheels
