Hi Guys,
We only have a few tuners down under so i am trying to gather an expectation of HP numbers. The build will consist of RS4 tbo, piggies, 3inch cat back S4 airbox mod, Bosch ev14 injectors and a tune running 20psi flat to redline with a mbc.
What should i expect and what should be the next upgrade to yield the best results ?
thanks
