Hi i am far from a technicel wizard

i have a WRX01 model with the ppp fitted i am curious about Mapping as some freinds of mine had there cars done and they say it makes a difference but is the ECU in my car ok or is it all ready at its limit Or am i just asking a stupid question

if not what cheapish mods could i add ?

Regards
Azy

 

So i take it i cant change it then

 

Your PPP has a piggy-back ECU thus if you are going to remap it you need first to take it off.
