What can been done without a reburn that is safe?

Electric fan, Headers, cat backs, water pump, thermostat, line mod for trans & so on. Just little things that can be done that is safe for the truck. I plan on going to the dyno in the next few months.

PS long tube or shorty headers for the best bang for your $$$$.


Thanks for your help in advance.

 

You can easily have those mods with a very safe tune. ANy of the tuners can set you right up!

 

Everything you listed will be fine without a reburn. The ECM is affected by parts that change the Air/Fuel mixture and the stock ECM can only compensate for certain mods that do this. None of the mods you listed do.
