tables for 03-04 cobra injectors

[Full-Force]

I have a heads/cam car over here now and the owner left some injectors out of an 04 Cobra for me to put in for him. I changed the IFR table according to the spreadsheet and the car drives ok but it will idle lean. Once you start driving its about right, maybe slightly leaner than 14.7 like now and then you may see 15.0 - 15.2.

The main thing is when idling it will idle lean until sometimes it pegs out at 18:1.

I believe the other injector tables may need changing as well, not sure.

I found 1 thread where a guy was having similar issues but really didnt see what I was looking for.

I guess I just would like to see what some of you have changed the other injector tables to and/or what you would recommend changing them to.

OK, I know atleast a handful of guys on here who are very knowledgable tuners. I really need this car gone but I would like to get it right first.

Any ideas on the injector tables other than the IFR?

I use those injectors without any problem. I don't remember having to change too much. My tune is attached, take a look.

Not many guys run them because the spray pattern is not ideal for an OHV motor.

Someone has to show me a spray pattern to prove that, the specs say different.

Ford rates this injector at 39lbs/hr.

The Bosch/Ford 0280156127 is a highly efficient fuel injector that incorporates a wide-cone fuel delivery.

Doesn't mean it won't work, from what I have read, it is not the most efficient spray pattern for OHV motors.
