I bought a 2008 F350 6.4. The truck had been del and tun-ed but the tun_er itself was gone. I am pretty sure it was an H@S. Before I researched things I found a used bullydog tun_er and loaded stock tune on the truck. In the mean time bullydogs support was walking me though something and the tune froze. We had to kill the in progress tune. I have since bought an X4 with cust tunz. My engine runs weird, on flats it runs great and great mileage. On hills or in the mountains the truck has no power and the turbo loads up past 40. I have had several mechanics tell me I need to take the truck to Ford to have them put the ECU back to stock and then load the cust tune and say I cant stack tunes but the person that I got the custom tunez from says it doesn't matter and that the tunez overwrite the entire ECU. Can someone tell me which is true. Also I changed the EBP sensor in the process. I appreciate any guidance on this.

Get another ORIGINAL H&S and overwrite whatever is on there now.
