Also keep in mind what people do to their stock SR’s without problems. Run say 12 psi (14 is supposed to be safe, I believe) and you’ve got the same increase in power.
i know its a slightly different scenario but it puts it in to perspective.
in the case of the audi thats only a 28% increase in HP.
in the case of an SR, assuming 180WHP stock (i think its probably a tad less in reality) you only need 230WHP to match that increase which can be done with nothing other than turning up the boost on stock turbo a little.
Then consider people are using the stock turbo and a good tune to get to 250WHP. (a good tune is essentially what that chip is doing, I guess)
