u need to get your re-mapped once its fitted

 

yes

 

If you dont, then it kind of hasnt really worked mate!

If it makes no difference, why bother fitting it?

but saying that, if your map is fairly safe anyway you will "get away with it" it just wont be optimum.

 

.....if your on an off the shelf chip then tbh they have enuff safety in them.

Good idea to increase the plenum size along with the throttle body and cooler ends to RS500 spec....the drivability improvement is well worth it.

...so yes without a remap you may notice a slight drivability improvement.

 

CAR HAS been lived mappped by a1 rallysport producing 427bhp so where do i go from here do i fit it
YES OR NO

 

what manifold you on at the moment?

2wd?

 

i would get it remapped just to be on the safe side and while you're at it stick a lickle more boost thru it

 

Ask THEM, only they know how it was mapped, anyone else is just guessing

 

what about transient problems?

 

Gareth...how many people switch from a 2wd to a 4x4 plenum?...Its gonna be about the same difference.....and only the absolute hardcore like yourself Gareth would actually bother fiddling with the map!

IMO of course!!!

 

spoke to karl about this for myself and the top end fueling could lean off so it would need to be checked at the least

 

are spacers worth having then?thinking of putting one on my car but do you need to modifie the inside of plenum so that most of the air dose`nt go stright down into number 3 cylinder?

 

wouldnt really be worth it at your spec TBH
