I installed a offroad Livewire with Innovatives Extreme Street tune, deleted the dpf, and dynoed an 08 6.4 for a customer today. I wish I had some dyno sheets to post up, but we had a couple of problems and I didn't record the best one. On the extreme setting we saw a peak of 502 hp and 10xx trq at 2900 rpm before we would set a code for low rail pressure or pull the restriction meter in. There is definately more hp there in the upper rpms, but the check engine light cut the fuel. Truck is bone stock except for the delete and dpf back 4". He said the fuel filter was due for a changing, so I don't know if the stock system just can't keep up or the filter is dirty. I am putting on a intake system probably next week, and we will give it another try then with a new fuel filter. I was definately impressed.
Oh, and the test ride was :redspotdance::bow::bow::rockon::rockwoot::rockon:
