His ewg is directly connected to the compressor. Yes its definitely sagging boost as well.

There is a great thread in here somewhere about where to source the boost pressure to avoid titty sag

I sourced mine just in front of the throttle body, as recommended.

Fae, dyno time is too expensive for some of the stupid fixes you had to deal with. Check your **** before you go to the dyno.

Nice numbers though!! It will be great once you get it all smoothed out.

Damnit I really thought my **** was nice and shaken down. I had 1000 miles at 5psi on it before yesterday. Everything changes at 20+psi though. Ugh I am also kind of pissed about those stupid new spark plugs. I should have just stayed with the known good type.

Regarding boost sag, I do not think that is what was going on? This is a graph from my session. See the boost line riding the vomit comet? It's not sagging, it's freaking out.



I also have a thread about this wastegate oscillation in the "general" forum here.

now that you have a good base tune, you can try to fix it before you go back.

check your hydra for overboost protection like said in another thread, check your wastegate feed.... TIAL says 4mm.. so if you have to stretch it onto the WG nipple its too small.
what are you running for boost control?
did you gap down the new plugs once you got rid of the race ones?


Be smart about it and you should be able to find the issue.
Its good power, but not smooth at all...

What's wrong with this picture- the circled item?



Going to fix it now. Free cunnilingus to the first person who figures it out.

This is the problem:



The gate was mounted backwards- with the valve facing the exhaust rather than the manifold.

I think a shop installed his ewg.

In any case, whoever did it should not be working on modified cars

Dude, I can't give you a hall pass on this one. How is it that you never noticed this mistake??

half the time and money he's spent on his car so far is fixing stupid mistakes.

No offense, but you should take like a whole week off and go through your car from bumper to bumper and just double check/fix EVERYTHING before you pay for any more dyno time. Some of the **** is just ridiculous.

I genuinely feel bad for how much time/money you've already thrown away due to mistakes.

Changed the oil. Rotella synthetic again since I had 2 gallons left.

I just went for a drive on the 20psi gate and it was great. I only part throttled it for 10-15psi and the powah is fantastic. Took some logs and boost pressure and knock ok and AFRs are decent. I forgot what it is like to drive a large-for-the-car-turbo. The stock turbo I have in my FXT is all midrange and no top. I think a big turbo matches the miata very well if you drive the car it was meant to be driven- up to the redline all day long. That was really the first "power" drive I've had on my new engine and I am very happy.


To do before next dyno:


Drill a hole for a 1/4" port in my throttle body intake pipe
Source MBC signal from that port
Redo the screws on my catch can- they fell out and the can fell off
I ordered like 600 feet of vacuum line from silicone intakes and will redo a few lines and clamp em down
I am going to go drive my car and pick up a 15psi spring combo and also some more t3 gaskets. Will install it.
I also bought a used harness to work on while my car is on the road.

I would get a weld in bung for the port. The charge pipe by it self is too thin to hold the port w/o leaking.

Any recommendations on decent fittings? I bought a $2 1/4" ID brass barb from home depot.
