i searched but really couldnt find answers , On the highway how is the afc hack at regular driving for long periods of time? should you stay away from like low 4th gear pulls? or will detonation not be a factor if tuned right

 

It depends on what you have it set at. Do you mean full throttle 4th gear pulls? There is a huge thread about highway driving with the AFC hack here somewhere.

 

for long periods of time ,like highway driving, and as for what its set at i would be runinng it like everyone else is on all the other afc hack threads with 450's
