Well I just got my car tuned it put down 347whp on a dyno jet and runs great once it starts. Every start no matter cold or hot it struggles and it sounds like air is being pushed back out the intake it'll do this once or twice when cranking over then it starts. Just wondering if its my injectors?

 

Edit : this assumes you have an AEM EMS

Check the value in the crank injector time table. The value should be around the same as 500RPM at 0psi on your fuel table.

 

turn the AEM ?crank inject all option off and it will stop making the "pop"
sorry my memory is a bit sketchy on the name as I have not tinker with my aem ems for sometimes now.

 

With my EMS I turn on the ignition and wait for my UEGO to cycle through its intro then press the start button.

 

Ok thanks alot guys I didn't drive it in awhile but I'll try those things once I get a chance.
