Bought a GLA45 AMG, now a Stage 2 tune?
New here from Australia!
Bought myself a stock standard 2015 GLA45 AMG kept in perfect condition.
Now I'm planning either a stage 1 tune vs stage 2 tune.Leaning more towards a stage 2 tune (+air filter & down pipe).
Not planning to take it on the track, just want a bit of fun on the streets. I've ordered an MST air filter and it's on the way

I've rang a few performance workshops here in Melbourne, Australia and a couple of them recommended using Redstar downpipe for stage 2 tuning.
I'm just wondering if it's a necessity or just recommended to use a heat shield for these downpipes?
- What maps are you guys running for a stage 2 tune?
- Is a TCU tune required also?
I know the car produces 265kw of power at the engine stock standard.
- Roughly, how much power increase should I expect from a stage 2 tune?
Thanks all in advance.
