Hi! Considering getting some after market fuel rails cuz as you know the stock ones are ugly!!

Do you need to get a custom tune if you get aftermarket fuel rails?!?

 

contact dave at brenspeed. these guys are great and they will definitely guide you in the write direction
im taking a guess that you wont need one, but i could be wrong

 

if you already have a tune, I'd contact that company and discuss it with them. If not I hear Brenspeed is an excellent tuner. If its the same output and everything, then I would guess not. But it's definately better to be safe and ask

 

No you don't need a tune for just fuel rails. Your not changing the amount of fuel or air going into the engine.

 

As mentioned in the reply above, you do not need a retune for fuel rails.

 

wow......

 

no need.
