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’m really about messing with a $47,000 truck with that stuff my question is what has everyone’s problems been with this set up?”
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.
“If you can’t pay don’t play, which u have a $47,000 dollar truck so you owe it yourself …. it took me around two months to keep things going,” Santander said.
One reader said he opted to check Banks + PDA. “I believe a dyno session is appropriate. I will give you the details when they are available. 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.
He added he enjoys the power it gives and he cannot distinguish the difference.
According to him, there are four reasons for this:
1) This often overlooked feature automatically reads EGTs and backs off power. Does the live PPE/EFI provide it?)
2) Easily detachable and no ECU residue
3) Anticipate some improvement on MPGs.
4) No gauges to install, just look at the PDA.
