LS1 turbo problem

[Kingston_99]

changes the injectors to bigger then stock?
just thought i'd ask

Try the plugs I suggested and let me know how it goes. I don't think it is leaning out. What you are probably seeing is just plain misfire as you describe, which reads as lean on a wideband sensor.

i tend to agree, tho they tell me that when it is on the dyno, they can see it is dropping a cyl, but I will def try the plugs and see how they go

try a plain copper plug as SN says and gapped to .8
is your 044 running off a relay?

 

[rubaduckee]
