2.3 Evo IX EF3 Turbo
I dont post much on here but I read a lot. Recently I had a motor that decided it no longer wanted to be alive so I ended up with a 2.3 L. While I was in there I also decided to change up some stuff on the head. I had the head ported/polished fitted with new 1mm oversized valves both intake and exhaust. Then the head was topped of with Kelford Cams 272/272 that completed the long block. So I had this built motor that was running on the stock turbo, stock intercooler, stock intercooler piping, stock intake manifold, and stock exhaust manifold had it tuned on E85 and it made 384/420 @29psi. I realized that my restriction is my turbo, this was at the same time that MAP was releasing the EF series turbos. I got in touch with MAP and had the EF3 sent over to me. This past weekend I had a chance to get the car tuned and the results were great for what was changed. Only parts changed were the Turbo,1650cc Injectors, and a single Aeromotive 340 pump, this is all on E-85. Car ended up making 433/400 @25psi peak due to the 16psi wastegate actuator not wanting to hold more.
This is still on the Stock Intercooler, Piping, Intake/Exhaust manifold. Also I will be trying out MAP's 22psi actuator instead of the 16psi one. As soon as I have more results I will post them up. As of today the car feels great it drives great and from what I have seen it is very capable of making 500/500. Big thanks goes to my tuner Bryan Medway for tuning the car.

yes my actuator should be here this week and in the car by the weekend and maybe ill have some numbers up by next week if all goes well. Let me know how the stiffer spring does. As for intercooler I am going to get one with a full pipe kit I also want to port the stock intake mani and the stock exhaust mani. This is like a second begining to my build if that makes any sense.

Yeah once the WGA is put on hopefully it will hold better. Hoping for 32 peak and like 27-28 at redline if not better. I also want to try SD on the setup and see if it helps out any.

Nice results...great peak power. It's tough to tell, being that this is a brand new turbo line, but does it seem a bit laggy? I read 25psi at about 4800 w/ a 2.3L. Not sure how this turbo was expected/designed to spool, or what it should be compared to, but for a stock frame turbo it seems laggy, especially for a 2.3L...Is this graph on par with the expected spool-up range?
I almost don't want to make this post because the turbo is so new and still considered to be in the testing phase. Not trying to bag on the turbo, I would just like to see what MAP and the OP think about how its spooling up according to their expectations, completeness of the tune, etc. We all know the EF line is going to be compared to the FPs and BBKs. This is MAP's "middle" turbo and to me it looks like the spool of a 2.0L Black.
I hope my criticism comes off as sincere and constructive, because I'm a huge fan of MAP products...my best regards to MAP and the OP in their efforts to optimize these turbos.

Also this pull is in 3rd gear. If you want to see an example of what the difference is in spool (and area under the curve) between 3rd and 4th check out this thread. Same motor, same dyno, different car, different turbo:

Another, with 3rd and 4th, on a 2.4L:

Notice the trend of +100wtq in the low end between 3rd and 4th in both those links
