I watched a teaser about TT RS prepared by a polish tuner.

Can anyone tell, what allows flames to appear at the rev limiter? (0:34)
Is it just the exhaust or also the remap?

Over fuelling can help, had a impreza once running 325 bhp, had an issue with a mass air flow sensor while I was at the tuners, it popped and banged all the way home sounded amazing and my pal following me said it looked pretty cool too.

But, apparently you can have an issue where too much fuel is injected which causes reduced about of oil in the block and I think the caused it piston shake where the rings start to wear because of lack of oil.
