Re: New toy, AU1 XR6. what to do
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.
