Truck hard to start, Starts easy on high idle

Ok, my truck cranks alot on any other setting but fires right up on high idle.It ramps a little then straightens right up. Its a 2000 f250 with 230k S&B stage 2 intake,4" proflow full exhaust,php custom tunes, swamps S/175/146 injectors,

Wierd. If you can handle this characteristic for a week while Bill is out of town, I'm sure he'll have a suggestion for you.

Yea i can handle it. I just thought it was kinda weird. It also starts alot easier even than just the stock ecm. I just had alot of work done and when I got the truck back i installed the tunes the next day.

I had similar symptoms. Make sure your fuel bowl is plugged in. Also was the work done at a dealership?
