For an SRT4-like performance, FiChry might want to take a page out of their own 1.9L I4 JTD Twin-Turbo Diesel, while working close to BMW's Twin-Power Turbo Petrol engines and employ the Sequential/Twin-Scroll Turbo to max-out the Tigershark engine for the modern-day SRT-4 Dart. Even if they don't officially call it an SRT-4, if they amp up the engine anywhere near the 2004 Neon SRT-4 territory that would need a special model name; at least that's what I think.
A similar arrangement might likely put out performance in the range of Subaru's 305HP. Not sure that's what's in the Tigershark if the FiChry Tuners would attempt such a thing. But I would think that a Twin-Scroll Turbo set-up on that car would about be the upper limit, short of a competition-built I4.

... yeah; posting this is sacrilege, I know.
