ECU limp mode

Okay I'm going crazy. I have a B16A Civic del Sol and I'm trying to upgrade the fuel injectors. The problem is I'm running 410cc with a ECU upgrade but the car will only start up on 20psi pressure on the fuel regulator. Car feels like it's in limp mode no horsepower at all. My ECU upgrade person is telling me It's a sensor. But when I put all the stock fuel injectors plus stock ECU the car runs great. Fuel pressure on 43psi 45psi. So my question is if it's some kind of sensor why is not acting up on my stock setup?

Re: ECU limp mode

Why does it need 410cc injectors?
If it's all motor the stock injectors are fine. ECU may be confused due to oversized injectors...just a guess.

I'm trying to upgrade the fuel injectors. The problem is
Stock engine?

But when I put all the stock fuel injectors plus stock ECU the car runs great.
Runs great? Bolt them down and leave it alone
