Decat downpipe
 

Hi guys, my Bugeye WRX have been modified and mapped by Duncan but was wondering if i remove my catted downpipe and installed a decat one would i need to get the car mapped again? Thanks

Yes, afraid so.

Should be just a map tweak so shouldn't cost as much if you already have ECUTEK 👍

Yes. Boost control will go mental and likely to overboost or even trigger boost/fuel cut.

Ah that suck thanks for the info though guys, will call Duncan and see about getting it done :)
