[Pandina]

Im having trouble finding a good tuner, can anyone recommend a tuner in melbourne?

Cars been great so far super fun only problem im having is the idle the rpms go up and down slightly around 100-200rpms dont know if thats normal doesnt seem like theres a vacume leak transmition also seems normal shifts super smooth.

Also what brand exhaust should i buy? Was thinking of xforce turboback want something not too loud

Any other recommend mods? i already have a k&n pannel filter and recently purchased a bov.

G'day and welcome aboard.
Have a chat to Merlin.Tuning@gmail.com
He is in Sydney , however , he maybe able to assist.

As for your exhaust I highly recommend to go 2.25 inch for the NA

Have a read thru this
https://www.lukey.com.au/pages/exhaust-size

Stock is 2 1/8th inch with a resonator
An exhaust is something you definitely do not want to go too big with
Your always better off slightly too small
Then slightly too big

The xforce turboback would make a good choice, depending on your definition of loud tho. My buddy has one on his and it sounds nice, I've got a custom 3 inch catback and love the sound.

As far as other mods, if you're looking for power and the car isn't already tuned then a tune is your best bang for your buck. Down the line you might consider the evo x turbo swap but then you need to be careful with your SST, all depends on how much power you want.

Enjoy your Ralliart, I know I love mine.

For the turbo 2L motor no more then 2.5 inch. Forget the cat back
The cat back does not add power as people seem to think.
The OEM cat is a huge bottleneck
You would be better off with extractors and a full 2.5 inch system mandrel bent installed for the RA
You will also need a O2 sensor eliminator for the rear sensor. The exhaust shop you buy it from should be able to fit it at the same time as the exhaust.
Get a high flow cat either 100 or 200 cell

If you want a decent muffler to keep it all under control with, I highly recommend a Lukey muffler. Buy an Aussie product and keep a fellow Aussie in a job. They sound great as well

As the car is a Ralliart and turbo you can comfortably run a 3" system. I think there is quite a few tuners in Victoria.

Maybe TMR. But I think they are pretty expensive.
