i have an 06 ram 3500 5.9l diesel. When I bought it with 14k on it ti was in crazy larry mode. I immediately changed it to tow/economy as this is my work truck and I constantly use it to tow 10k to 15k for extended distances. I just had two injectors fail that took out the motor at 30k miles. I thought I set the truck back to stock mode but didnt do it right and the dealer figured out that the truck had been programmed when he test drove the new motor. he threatened to void the warranty and make me pay for the motor but thats another story. He says the bully dog caused the injectors to fail. Does anyone have any experience with this. I am hesitant to re-program the truck, but it is really slowing down on the hills when I am hualing.

can he do that. . .yes he can simply cause he know youve got a programmer on it.

was it the programmer that caused the injectors to die. . .probably not, however it does give ammunition to the dealer to void the warranty.

as far as your truck bogging down on the hills. . .sounds like your not getting enough fuel to the CP3. might need to get the in-tank pump checked out.

I had a bad experience with Bully Dog trial software and my old truck. I could nnot get rid of the trial software from my computer. I would not re-install the BD programmer. If the engine is brand new it may need some time to break in before it is up to full power. BTW my truck ate an injector already and it was stock when it did so.

Take the Bully Dog off and don't put it back on. I have seen the BD system kill more engines than all other programmers combined. The injectors are considered a STAR part. This means that the Tech has to call the STAR hotline to explain why he thinks it needs an injector. The hotline will require the Tech to run a list of tests to justify the repair. The Tech has to input the VIN before he can talk to someone at the hotline. The hotline guy always ask the Tech if there is a programmer on the truck. If the Tech says yes, the hotline guy can void the warranty. If the Tech lies and the hotline guy gets suspicious, he will ask the Tech to hook the truck up to the diag tool and transmit test data over the internet. If the data revels a programmer, trouble is soon to follow. Dealers do not liketo seethe warranty voided, afterall, they are the ones who are facing the angry customer. If the dealer does an unapproved repair, the dealer will get charged back the entire bill. The dealer has to send the damaged parts in to be inspected. If it is determined that a programmer or other non-approved "accessory"caused the damage, the dealer will be charged back the entire bill, even if the repair was "preapproved".
