Hi,

Are there sufficient tolerances built in to the PPP upgrade to allow for minor performance upgrades wihout have a detrimental affect to the performance e.g.

Changing the back box for something a little more fruity?

Changing the airfilter for a cotten Sti Panel or foam based?

Replacing the restrictive downpipe at the front ?

Cheers

 

Yes the PPP ECU is quite adaptive and safe but don't go to extreme solutions, of course you loose your warranty if you forgot it...

As the injectors are already running flat out, the answer is no unless you want to take a risk on it running lean due to not getting enough fuel when it's really needed. Any increase in boost, as you would get in some circumstances with a different downpipe, may put it into overboost with a resultant CEL.

Did I mention warranty as well...........?
