Update to the latest tuning. I posted about it a while back when I was running the Pre-release tunes from Ryan..
With the old tuning you will be blacking out an intersection with the MP-8 turned up. I run the highest tune (performance now) and I have a little haze when I get on it even with the MP-8. With the new tuning its a lot cleaner, power is more linear and once the turbo lights it takes off.
If you decide to keep the old tuning, it's been shown that the "wild" tune will make about 50hp over the "hot" tune with the MP-8.
H&S has made it very clear that they will post and make it clear before they can no longer offer DPF delete tunes...as it stands their tuning still supports DPF delete and I don't expect that to change anytime soon, if at all. You know they do also offer custom tuning
