2.4L FP Black DBB (Twinscroll) S3 cams E85 31psi
Its always a pleasure working on a setup that has zero bottlenecks. This car makes really good power per boost, and between me and the customer we decided to keep it where it is boost wise to keep the car reliable.
If pushed I feel this one can exceed 700 no problem.
Mods are:
2.4L
FP BB Black (Twinscroll housing / Mitsubishi OEM)
GSC S3 cams
Dual inline external walbro 255
FIC 2150cc inj
Ported em/im
Map o2 dump eliminator dp
Full catback 3"
milspec 65mm tb
upper and lcip
ETS IC
AMS fuel rail
4.11 FD
Tephra v7 speed density /w hybrid boost
Graph and video below:
Any questions feel free to ask.
Injector duty cycle on this one was a max of 83.8% @ roughly 12.2-12.5 AFR
This AFR is for drag style type events. When flashing the other rom it will drop about a full point richer for him for longer duration type style events.

Save your money. The stock intake mani's on these cars are good for something like 600-700hp IIRC from some other threads. You can send your stock one in to Busher for a port job and that's about all you need. That's what I have. I also have stock head. Again, save your money on headwork unless you need a basic valve job for maintenance.

lol I bet. Mine drives like **** in 5th gear right now, I get surge. How did your inline-external fuel pump setup hold up? Were you close to maxing that out or did you still have plenty of pump? I ran out of pump on my 450 which is why I'm only at 27psi. Left about 100-150hp on the table thanks to not enough pump lol.

if buying a Magnus didn't result in awesome gains, I'd agree, save money. but they make more power

Using a ported OEM FPR and ported TB will net about 15-20WHP across the RPM range once in boost. An AMS VSR will net you 30-40 at the expense of lose of spool. No free lunch. On HUGE Turbos I have seen a VSR gain 70 but this was crazy boost on race gas.

I have to double check with Tom, but injector wise I was originally running the 1650s and those were maxed out quick, so the change over to the 2150s was best decision, and drivability is great
