New up here

I just purchased a 99 F-250 7.3 i have the k&n intake, 4" turbo back strait exhaust, banks bighead wastegate actuator, and a DP tuner but i was noticing some wierd issues with the chip. Like a strange lope to the motor at idle and some strange down shifts so i got a SCT tuner and unpluged my DP and the problems went away could you stack those chips?

I dont know exactly what i have i just know what the previous owner told me that it has the settings like this.
1-Stock
2-40
3-60
4-80
5-80 economy
6- 120
7- 140 agressive

But i feel like i gained more power with the SCT but both programmers have the feeling that i have alot more power then is getting ot the rear wheels and the local diesel shop says that my torque converter might be going out but the truck only has 68,000 miles on it?

it could be going out depending on how the previous owner treated the truck and if he kept his foot in it at level seven the whole time.

From what you are saying it sounds like the IPR or ICP sensor may be bad. Have you checked for any codes with the SCT? Jody is asking for the max in your tuning, so you may be noticing that over what has been done in the tuning of the SCT and stock. Because he is asking for the max, no stacking of chips and ICP mods are necessary with his tunes. The downshifting is a part of Jody's standard tunes. If you don't like it he can remove it.

The other thing i noticed when i run just the DP is when the truck shift gears it falls flat on its face it blows off all the boost. When i took the DP off and installed the SCT it took that problem away that was the reason for the big head wastegate actuator maybe i need to get DP to flash the chip and make sure its right. It was on the truck when i bought it and the boy that had it didnt seem to know what he was doing.
