Turn up 3406e or not?

Fuel temp sensors work good at adding HP. Boost sensors male for a more responsive fuel pedal but makes lots of black smoke because of the initial over fueling. I have used both. No engine damage can occur from these plugs

 

Fuel temp sensor is a temporary fix. It only works until your fuel get up to operating temp. Boost harness only makes it smoke.

 

Idk if I'd want to push for too much more power when you say that Cat won't uprate it because the components are at their limits. Don't know how well it would stay together.

 

IMHO if it isn't broke don't touch it. I pushed the HP on my 3406B snapped three exhaust manifold studs, I turned it back down after that.

 

Likely with that early of an engine it has aluminum pistons and odd ball hardware to go with(cam,injectors)

 

Leave it alone. My two cents

 

No, doesn't work, in 5 min after you plug in the fuel temp harness your engine fan starts , and never stop , unless you remove it, about the other one doesn't do nothing beside smoking
