Sorry for the slow response I have been reading and researching....

Ford Yellow tops are the wrong injectors they rate at 19lbs/hour 202.0 cc/min original equip rates at 23.67 lbs/hr and min of 195cc/min. On the per min flow they are close but the original equip number is the minimum flow and the ford motorsport doesn't say which it is so it's possible that they could cause a problem. The ford motorsport injectors you probably would want are FMS-M-9593-A302 they are 24lbs and 255cc/min.

To low of a flow rate could cause a lean condition. But the information your giving muddies the water so to speak. Dap is saying it's running super lean, but they also say they can smell raw fuel dumping out the exhaust. These statements contradict themselves. Lean does not produce the raw fuel smell rich does. So the question is then which is it? I would be curious as to what the spark plug looks like when pulled...

There are quite a few other things that concern me in the reply but I won't get into that.

So now on top of it the parts guy says you have low compression? Did he give you the results of the compression test? Had they mentioned this before?

Honestly get the truck out of there and lets set up a time that I can drag smarter than me people up there and some spares to get this thing going. I have a nagging suspicion that it's something simple and just needs some attention to detail to get it going.
