I am having the same thing happen to me.

A friend of mine following me, saw a lot of black smoke coming out when I went from 80 to 120 mph. All I did was depress my gas paddle to maybe to 1/2 in 5 gear.

Will an SAFC fix the problem and add power?

thanks,

 

Thanks Claudious,

What about reliability, would you expect any problems if one sets it between factory and maximum allowed? I don't want to have do any engine work on this car due to mods I may add to it.

thanks,

 

SO is this normal and ok for our cars, or should i be worried? Black smoke.
