hopefully this will be the cae when I have it dyno-checked...also curious if the fuel pump is adequate for 200 shot...may have to do boost-a-pump or another intank pump...right now a single Walboro 340 GSM with hotwire kit and voltblaster, stock fuel system otherwise.

will keep results poseted if this is not due to additive. Hoping for 10.5's at 132 at Norwalk...have to wait and see...

 

Scott,

The red tint is a characteristic of the Torco Additive. Typically, a nice medium tan with no speckling or pitting is a "good" plug. Since you're not showing any KR and we're not too crazy (YET) on dosage, you should be fine. We will learn more on the dyno later with the wideband plugged in.

Editted for grammar.
