Car dies at idle
Back story first, I ran AEM ems since 2005 on the car when it had ITB's and then a few years later I removed them off the car and continued to run the EMS. Wit that being said things have been re wired taken off removed put back on etc. The other day I Installed a Mugen ECU. The car starts up and drives great idles but it seems to run a bit rich judging by how much fuel I used on a short drive. I still have not put and OEM fuel pump on it it has a 255lph. Could this by the cause of the large amount of fuel used since the ecu is tuned off a stock out put and the I guess the AEM was tuned accordingly to the fuel flow? Or does the stock regulator regulate it regardless of the flow from the tank? You start the car and and it seems to start fine and idle fine then when you drive the car and come to a stop the car will idle and then hiccup and stall out. Could the engine be loaded up on fuel to cause this? Or should I look elsewhere TPS MAP O2.... Thanks for some input

it was full and a zeroed out the trip after I filled up today drove 40 miles and then it used a 1/4 of the fill up mean while my wifes car has about 90 miles at the same spot on her fuel gauge and averages 120 + at the half tank mark. So I would get about 80 miles at the have tank mark maybe at this rate.
