pull 4-5 degrees out and start from there evev if you dont hear detonation .. check your plugs often. Do you know what it sounds like? U will hear a light rattling noise souds almost as if its valve ticking or somone rattling a can tab they dropped into a beer can ect

 

4-5 on a 100 shot? you'd spray it and go slower

 

I had a 150 on my old fox and it ran fine with timing a few degrees lower and a fuel pump. Went to 180 and fuel pump went out and so did the bottom end

 

spray the hell out of that 250dollar car

 

Dats wat Im sayn!!! Spray and watch it blow!!! LOL!!!

 

its RETARD 2-2.5 degrees per 50 horse sprayed to start saftly then u back off aint it

 

good luck keeping the 5.0 SO and aod from blowing up but for 250 blow the bitch up and get a HO motor

 

FYI, you won't get much more than 150 through the average nozzle.

< doesn't use an average nozzel!

 

Spray it till it breaks.
