    It can due to the change in CFM. For optimal performance i say get a retuned ecu. By the way is this Eric as in AccordR33 or Eric from Ericks Racing?

    P.S. If its the latter, someone should kick you many times. j/k

      you can drive it just stay out of boost. How far is the dyno?

        Thats easier said than done with a big evo turbo. Does that thing start boosting just under 3k? Or maybe around 3k...Hmmm (I'm about to go out so I can't search this and make sure).

          oh and if u want a very good safety feature...just disconnect a charge pipe, you don't even have to take out just make it so can't really build boost. If the ecu doesn't read boost then it won't dump in fuel to compensate for it.

              well yea the Manifold Air Pressure Sensor reads the pressure and the distributor sends the rpm signal. The ecu accepts and calculates the two and sends a signal to the injectors to open for X amount of time. So if the MAP sensor only sees 0 vac it'll only send the fuel programmed into the map for 0 vac even tho the turbo itself could be at like 20psi

                  why would it make the car run shitty? Just put an air filter over the pipe that leads to the engine as if it were n/a. It'll run exactly the same

                    yeah, or even switch back to stock ecu with charge pipes connected, then when you hit the dyno, put the charge pipes on and chipped ecu in.
