I think if you changed to 1zz injectors o 4psi, you should be fine. Going to 1zz gave me a -15% LTFT throughout closed loop, so I'm interpreting that means it's putting out +15% more fuel.
Looks like i did this run 4psi, 0 fuel, but pulled ignition timing by -4 degrees

Changing the injectors will help until the system "learns" that it has extra fuel and trims it out. That only takes about a day of driving to happen.

Does the factory have enough authority to yank back that much fuel? If so that is awesome. This may speed things along for me until i can afford a patch harness for my AEM

It's not so much an issue of authority as it is PWM frequency range. In theory it can do PWM from 0% to 100%, but it could be artificially limited to a smaller subset in the control loop. It's likely to be controlled by a PID feedback loop (the same thing that keeps a Segway upright) that targets 14.7 AFR, but the coefficients might be such that they can't cope with dramatically larger injectors. I recall Lt Noogie trying the big grey injectors from a 2.4L engine and it ran too rich almost all the time, constantly throwing CELs.

My brain hurts every time I read these posts... I figure, if I read it enough times, it will hit me like a dump truck and that light bulb will finally shine brighter than 1,000 suns

Hoping to find out this in the coming months. I have everything I need. Including a patch harness finally. So if the car does not like things...slap the AEM and have her tuned.
First thing is the clutch...

I'm not sure on the newer computers but the older ones in the echo will only trim 20% max.

Yes. The Blitz (and my ineptitude at driving a stick) killed the OEM clutch after about 2.5 years. I got a Clutchmasters stage 3 and it's been awesome. It took a week or so to get used to the additional pedal effort, but it's well worth it to be able to hook up and run hard with those extra horses.

I ran a ACT 4puck with a HD cover in my tercel and loved it. Pedel effort went up marginally over stock.
Probaby going to get a full face ACT with a HD cover

Personally i find the the additional pedal effort along with the performance copper clutch disc makes for a more normal feeling experience especially with the dbw throttle when engaging the clutch from a stand still

Thats because it needs to have the Fletzer bearing reamed,routed and rotated for a free flow press fit.

So attempting low boost is not going to happen.
Found out my wastegate actuator is 7psi...and I not spending money to get a lower one. Just going to have it tuned at 7psi and leave it. Its coming together gentleman. I am excited, and hope to have it all done by spring. I start fabricating the intercooler and charge piping next week

You can lower the wastegate spring pressure you just have to cut and add to the bottom of the housing. This is mine from the MR2 CT26 turbo. I'm not sure what stock boost was set at but I doubled the length and it now gives me around 6psi of boost. It starts to open at 3.5psi when I bench tested it.

I would think the heat from welding would damage the diaphragm?
