Would it be benifical to remap a standard zed, only upgrades are exhaust and air filter, and if i was to purchase an electronic boost controller do i get it mapped before or after IE : which comes first ?

same time really,

 

 

get it chipped/mapped, then incerease the boost.

 

 

you need to get it chipped mappt to run increased boost tho..

get it chipped first or get it custom mapped afterwards. chip is about 100 and custom map is 500-700
