Chris Kristofferson from Iowa is a bonafide diesel truck fanatic. He drives a 2008 GMC 2500HD SLT X-Cab EFI. Kristofferson is concerned whether to maintain or remove the DPF Delete Kit which he had installed on his $47,000 truck.
He posted on a popular diesel truck forum, “I’ve been reading everyone’s posts about throwing the DPF in the trash using a PPE programmer and going turbo back exhaust. I’d love to do this because my ‘06 was straight piped and chipped and I really miss that crazy power being able to pass anyone on the highway with ease. I cannot understand the problems encountered by others with their $47,000 truck?”
Kristofferson explained that buying a six gun and PDA with an MBRP DPR back exhaust is a good alternative although it cannot provide the same power and performance.
“The good thing about that though is I’ll be able to adjust on the fly,” he said.
Alex Santander of North Carolina, who drives a 2007 Chevy replied that ditching the DPF Delete Kit was the best move he had ever done.
“An expensive truck really deserves to be taken cared off …. I spent around two months to keep things running,” Santander said.
Another reader said he was more comfortable using Banks + PDA. “I am thinking of using the dyno session and will update you with the result. I’m in colorado so the numbers will likely be lower than elsewhere — but the % gain should be relevant. If I were you, I’d just wait a couple of months.”
According to the post, he would most likely dump his DPF Delete Kit at the five-year mark when the warranty’s up.
“Unlike you, I really like the power I have and don’t know the difference,” he added.
He offered four reasons why he believes otherwise;
1) This often overlooked feature automatically reads EGTs and backs off power. Does the live PPE/EFI provide it?)
2) It has no ECU residue and can be detached easily
3) Anticipate some improvement on MPGs.
4) No gauges to install, just look at the PDA.
