Air intake and exhaust system changed, need mapping?

[Sxndric]

Hi, I put in an aftermarket intake and exhaust with a 200 cell cat, I've noticed the car doesen't really pick up power that well anymore, does it need to be mapped? And how safe is it to map these engines?

Doesn't 'need' to be mapped if you can live with it, but mapping will help and you'll certainly gain performance, especially in the mid-range. Mapping is only as safe as the person doing the mapping. RS Tuning and EFI are the two most often used on here.

Okay thanks, I know an RS specialist around here so I will just take it to him for a remap, should fix the so famous flat spot.
