car fixed but misfires...?

[desolateboosted]

Ok I have just finished fixing my car.

info on car

-rebuilt stock
-removed balance shafts
-scm61
-supporting mods

It runs and drives fine but when boost comes on around 4k it starts to hesitates, studders, and pops. I have to let off because it misfires soo badly. There's a cloud of smoke that comes out. Not sure of the color. Looks tanish. I reused the spark plugs so I'm thinking it could be that.

Had same issue, replaced with NGK BPR7ES. Check to see if their is any carbon (white) coating in the plug wires causing a gounding condition while switching them out the plugs.. I think I got my plugs from NAPA for like $8 and some change...

I'm going to try new plugs tomorrow. I'll let you guys know how it turns out.

Wait a minute......You ran a 12.00 1/4 mile and you don't have injectors or a fuel pump.

I'm waving the bullshit flag here. Ah, crap, there is no BS smilie.
