1G Bigger intake, exhaust stock ecu?

[Adrian97]

Hello!
Can i change stock IC and Piping to VRSF and exhaust to 2.5-3" without any ecu change, I mean do I need any ecu tunning or remapping?
Riding on stock ecu with bigger IC and piping and Exhaust does not affect the engine badly or something like that? (Idle bouncing, run rich or lean e.t.c.)

You should be fine with stock ecu! In these cars unless you start messing with fueling timing and big boost stock ecu should be able to compensate for minor changes.

Generally yes, since it is a maf car. Long as you don't screw with the maf/inlet pipe. However, a side effect of the mods you suggest I'd increased airflow/boost creep. This might put you into fuel cut. Also make sure you have a boost gauge to check, and a upgraded fuel pump along with a fresh filter.
