Hi, I just bought a series 1 au xr6 base model with a few tickford acceseries. What mods can be done for what type of money , value for money. Ive been playing with carbied V8 so these computerised 6's are all new to me.
For 1500 bucks you can get a decent extractor and exhaust set up,
Around 400 for cold air intake,
And to make it all work well a custom flash tune I think is available now for the AUs, expect around 1400.
This will make a very noticable difference and is relatively cheap and easy to do and has been tried and proven by thousands.
