Ecu Stegea 4 Wd Light, Suspension , Exhaust

[Aps]

I need some general info on replacing the ecu and how much this improves economy . Give us an rough cost involved for someone to replace it . I have a 01 250 t rs4 stock it could be a bit better on fuel knowing they are a thirsty car generally .A few other things while I'm on the forum for the people who are way more technical minded than me ; 4 wd light comes on intermittently ( dealer reset the comp and found no fault ). Auto trans , are the adjustable as the car kicks into second on slow turns into streets with normal driving and only wants to go into 1st if you really gas it ,it may just be the trait of the auto on these cars .

What is a quality muffler for these cars that resembles the factory twin tip ( mine sounds fine but only one seems to have any flow to it .

Lastly can u recommend a quality touring suspension upgrade and where in Adelaide would you trust to have a detailed check on the existing set up ?

Cheers Aappreciate any advice...

Can't wait till they start hammering those v8 nissans around clipsal !
