when should i fit my 440s?
 

im having my headers and up pipe and also a front mount fitted soon.should i have the 440s fitted when i get this work done or leave it till it gets mapped?got to travel 100 miles after the works done.

imo leave it to the day or day before you get it mapped then drive off boost to wherever you're getting it mapped.

Defo as above and keep it off boost driving to the remap!

You can still fit the 440s because the ecu will still feed the same amount of fuel to your engine
