Hey Guys

Got an Ed xr6 turbo with an EL xr6 engine in it.

I've got issues which i am sure are sensor tune related but can't pin point.

When starting the car it runs like s**t for the first 5 minutes or so in the mornings when it almost flicks a switch and runs sweet.

If it's already been running and i turn it off, then start it back up it will run like s**t again for another 30 seconds or so then again starts to run ok.

Seems to be that its flooding with excess fuel during that period so i lose all power and popping a little. I know the ECU's have like a cold start setting in them which i believe add's additional fuel. Can i turn that off or is there a sensor that the ecu relies on know when engines cold or to add that additional fuel?

Ive got a J3 and programmer, tune is a rich boosted tune from TI and im leaning it out as i go which is working fine when the car is running as it should.
