I checked it when I was done and ever fell below 48. Runs great now

Thanks bud, that's great info to know. I had a hunch there was something else because even though the voltage was a touch low, it shouldn't have made it run that poorly. Amazing how such simple things WILL make these trucks run like such crap though isn't it?

Yeah it is. The wire harness that i got did not look as good as mine did but the plugs where alot better for sure they snapped in and where alot easier to get on. hope this will be the end to that problem! i am gonna try the rotella t5 next go round to

I just tried the T6 this go around, truck runs really smooth with it. Still have crazy stiction going on, but I blame that on my 4 pin FICM I have in right now, have to figure this 7 pin out that I fried accidentally. :argh:

I hear ya. I found that I can get the t5 at the tractor supply for the same price I am paying for regular at SAMs. So I am going to try it next time. I am going to put new air filter in soon mine still don't look dirty at all.

You running the stock filter still? Just leave it til the filter minder gets sucked in, it will pop up on the dash saying "check filter" or something when it does.

I guess tractor supply is having some big sale on all Rotella stuff right now, they had the T6 for like $17 or $18 a gallon. I just paid $27 a gallon a few weeks ago.

Yeah stock filter still. no light on yet so i guess its good. I dnt know if its on sale here or not but its 14$ a gallon for the t5

The stock filter is suposed to be good for 100k, it is a quality unit, the main reason I got the Injen unit is because I can clean the filter and I can remove the whole thing all the way to turbo in about 2minutes/ try that with a stocker:w2:
