car sputters and hesitates

[turbobeast707]

I have changed my injectors to 80# injectors with matching tt chip, scanmaster. Im not getting any unusual readings on the scanmaster but I am getting a check engine light when I accelerate and when I come to a stop does anyone have any ideas. the car hesitates when I punch it at all and sputters when the rpm's are coming back down? the check engine light doesnt stay on it flickers on and off and at these times and doesnt register on the scanmaster or on my code reader... im out of ideas..

Check to see if you installed the MAF sensor in backwards ?

Is it possible the ECM chip terminal prong might be bend during installation?
Also check and see if the fuel pump can handle those injectors; you might need a double pump
Check all of the fuel system and gauge to see if you are getting the correct fuel pressure

Running a walbro 340 fuel pump is it capable of handling 80# injectors?
also MAF is in correctly.
Thanks

Are you answering me with a question?
That was my question to you, to see if the fuel pump can handle those injectors
I believe I read somewhere in the thread a walbro 340 fuel pump can handle up to 60# injectors, but I could be wrong.
