Auto enguinity should read duty cycle of the hpop, does your cousins truck do the same when the chip is off the truck too?

 

Ae will read pressure and duty cycle.
Check those and fuel pressure.

i have heard (don't know how true it is) that bullydog will leave a program on the PCM when it is removed and it will need to be reflashed

 

Can AE check to see what his HPOP pressure is? I think I read that if the HPOP press. is low, the injectors wont be able to fire as well as they would under proper pressure?

Yes; it would be called Injection Control Pressure.

Also, does he need to get reflashed since the bullydog was on there? I think I also seen where IDP said you should but I havent seen it anymore after that. Its just hearsay...

As long as he did whatever "command" on the Bullydog to revert the PCM to stock, there should be no need to reflash.

the story is a friend of mine had a SD (not quite the same) and had a bullydog chip got a ts style chip and it ran as stock on all positions, he did some looking on the interwebs and found people saying that when pulled the bullydog leaves leaves a ghost program (for a lack of a better term). my friend then went and had the PCM reflashed with whatever program was orignially on it and the chip now works. just what i have heard/my friend's experience take it as you will

 

The chip should also overwrite any tuning from the programmer, correct?
