XRT Pro DPF Attached Performance

Just installed the XRT Pro with my DPF still on. Not what I expected. On Hot (120 Horses) it just doesn't seem to be giving me what is advertised. Full throttle i'm only seeing 20 or 21 psi of boost max. Is that because the dpf is still on? Is anybody else running just a tune and no exhaust? If so what are yall seeing?

Just deleted last night. H&S mini maxx, s&b intake, AFE 5" with muffler. On hot setting it is unbelievable. I run out of road before i run out of power. From a 20mph roll it feels like it is going to rip the tires off and just puts you in your seat. I am not sure of MPG gains yet because i cannot keep my foot out of it. I was nervous about deleting from my truck (only 7K miles) but it is amazing.

No, I had the intake for a while and just did a full delete. I didnt have the mini maxx on the dpf present, just dpf removed. I was worried about the smoke, even on HOT and when you mash it, it just has a little smoke but its not billowing out like the older trucks. If you drive it normal its fine and not even loud.

I have the XRT Pro and DPF delete. Everything else is stock. I havent went any higher than the mild setting at this point. At WOT the stock boost guage reads about 30 psi max.

I deleted for MPG when towing and an overall more reliable truck. I am happy with the whole set up.

Get rid of the DPF. I did the same thing you did for a few days. Once I took off the DPF, it was insane. I'm still under factory warranty for another 10k or Dec 2013. If I need to go in for warranty work, I'll either go to a "mod friendly" dealer or just put the stock exhaust back on...it only takes 30 minutes to make the swap. Get rid of the DPF. Everyone says it for a reason.

Yeah I talked to the guys at H&S and they said the same thing, the dpf on and off tunes are completely different. The advertised numbers are correct but he said with the dpf off tunes they could really get aggressive in the low and mid range whereas they couldn't with the dpf on. Boost numbers would increase too. Ordering a dpf delete pipe as we speak.

How is the sound level? Does it shake the house when idling? I am talking DPF and CAT deleted.

Sound level is good. It's quiet in the cab and I don't have any drone when driving or towing a gooseneck. It's loud enough outside the truck to be noticed but not enough to piss everyone off. I have a 4" straight pipe...seems like most people on here go with the 5" which has a deeper tone. The 4" has better performance though until you start making HUGE numbers. If you plan on upgrading injectors, turbos etc., I would go with the 5". Otherwise, go 4".
