best turbo setup for 350-375whp

Had (2) S4's and each twin scroll didn't work. The actuator bolts snap, vacuum hard lines rot or get pinched, etc. Still made boost in a really low rpm. Don't know what the fuss is about. Maybe I'm just use to high rpm 600cc street bikes and 2-stroke dirt bikes where your always on the rpm's anyways.

Well I've seen a guy with just over 400whp with a 2.1 , it probably depends more on the users ability to tweak things and get it running to.full potential.
For my car I'm not sure what to go with, I can use all 550's or 550 primary and 720 secondaries (from gsl se).
Ill be running like 9 lbs Max on the stock ecu and fuel pump with a fcd.
I'm not sure if its even worth getting the 1.7 rtek to run 10psi or worth it to run the bigger secondaries on 9 psi or less (figured more fuel is better even if the pump is stock).
Then again I could just run low boost like 6-7 psi so I don't risk running lean.
What do y'all think would be best for my initial setup as far as boost and injectors for my near stock setup.
Car is s4 has full exhaust and s5 Turbo. Idk how much I'd have to port wg to run near stock boost on full exhaust. Intake will be stock.

main draw back is the limites of the stock map sensor, and the restrictions of the afm, and a rather tedious entry method of tuning

I came to the conclusion that the powerfc is more expensive, but a way better unit. It is also plug and play (might need a banzai kit if fd model). My tuner knows it well too. Good option for me.
The rtek is cool, and I did consider it for a while. But honestly, I'd end up spending money twice.

+1 on the PowerFC. I was going back and forth between Rtek and a true EMS. Nearly everyone I spoke with, including Rotary Performance, suggested the PFC for it's easy plug and play and tuning abilities. For your goals, I believe it will be more than able to to get you there.

as always it depends if you are going to tune it yourself or get it tuned by a shop. if you are going to use a shop then ask the tuner you use what EMS they are most comfortable with.
as far as ease of installation and learning curve i generally recommend the microtech LT8. they are the cheapest option but do require some wiring, but they do work with the stock sensors and wiring clips so there is no hidden costs. their drawback is that everything is firmwared into the ECU, what you buy is what you get and you cannot reconfigure it on the fly like most other common EMS on the market. you also cannot download and save base maps to a computer but they are coming out with a new ECU that has that capability for the same cost.
microtech is by far the easiest to tune, no one can really argue that. it's very easy to get distracted in the haltech software for example with the 10,000 optional tables to turn on and off, most of which you don't really need. the downside with microtech is you have only the default basemap so you are knee deep in learning to tune to even get your car driving right out of the gate, if you have a stock setup it should run and drive without messing with it much but who really installs an EMS on a stock car?
i have been looking into the adaptronic EMS and have been contemplating becoming a reseller of their ECUs but i wanted to get some feedback on them first. they do have some nice options for a good price(E85 adaptive and autotune features). unfortunately they don't offer a plug n play for the FC(why the **** do FDs get all the nice **** when they are the minority...). but realistically you could use the adaptronic on a S5 turbo with the banzai adapter($300 wasted if you ask me, if they would simply add different ECU plugs they would sell more).

then they should update the website and i also did not see Elliot make any mention of the S5 plug n play ECU. it also still leaves the S4 turbo out to dry, which is the most common model of any turbo rotary ever produced.
There are direct plug and play ECU(s) for Series 6/7/8 Rx-7, and Series 1 Rx-8. The Rx-7 units use the OEM connector, just like the PFC. The series 1 Rx-8 has a patch harness, and is used in conjuction with the OEM ECU( handles drive by wire, idle control, and communication with ABS, Dash, and Stability Control).
perhaps what you saw was a patch harness to plug it into an FC, which is still the above mentioned $250-300 on top of the ECU, making it an even less desirable option for FC owners. i personally look at other options before the PFC because of this additional cost in the past. the FC has a lower resale so keeping things on at least an even playing field will yield more customers.

I will admit that using Palm OE, you do have to have patience. Maybe being an "Old Hot Rodder" may have some advantage after all.

pre-cat and main cat? that's a lot of restriction for what's being thrown at it! Can't see having all that high HP hardware and corking it up with them cats.
that's what pisses me off about CA that I can't put 2 cats in parallel to allow the exhaust smell like roses while limiting power loss.
