Default Running extremely rich and already burnt plugs twice!

Some one help me. I have a Nitrous Works wet kit with the following


Tuning by Jayson(MTI) with 24 degrees of timing and Im running EXTREMELY rich

Vortex Fuel Pump

MSD WIndow S. 3 and 6

I just dont know what is going on. The first time this happened my car burnt a valve bc it hit the limiter, SOLUTION: MSD window switch, pulled back timing and Richened it up Max.

Now it has happened again. I disinegrated 2 spark plugs AGAIN.

150 Shot of Juice. Wich is equivelent to probably a 120 TNT.

Someone suggested something is wrong with the Fuel Solenoid?

is it the same cylinders that are always burning up? What did your a/f say on the dyno? Could the fuel solenoid be operating intermitantly? You are obviously going lean and/or detonating in those cylinders.

I would run some race gas if you are going to continue to trouble shoot your system until it is resolved.

Ditto with 383, rich ***** up the plugs, which nitrous is really good at cleanign them.. Lean however fries 'em. What kind of plugs you running? using a 150shot, you need a colder plug, and then the right gap as well.

NGK TR6's gapped at 40. Yes its the same cylinders that are burning up, not sure on my AF.

Anyway I have decided to go all motor so MTI tuned my car all motor. I would like to know what the problem was. Ill ask MTI what my AF ratio was though...
