First off let me give a little history. About 2 months ago I blew HG's and got it studded, at that time I had the injectors flow tested and they said that they where not flowing enough on the high side and that they were almost gone. About a month ago I got Eric to tweak my Extreme Street tune. I uploaded the new tune and that is when this problem started. First I noticed that it had considerably less power. I uploaded the original Extreme street and still the same thing, a lot less power. I figured that my injectors had finally got bad enough for me to feel it. I got me a set of 155's from Jesse Warren and installed them. Got all of my tunes updated for them. Fuel psi was low after that, ordered an Airdog 2. Got it put on today, 62 psi fuel now at idle and WOT. Still no change in the lack of power. I return the truck back to stock and drove it down the road about 6 miles, it ran as good as they do on stock tuning. Got home killed it and now it will not start. I have 0.6v ICP while cranking, 62 fuel PSI, no codes. Also ever since this started I cannot get my EGT's over 1200 and that used to be really easy to do. Also I am draining batteries like crazy now, they were only 4 months old. I let my truck sit for 2 weeks while at work, come home they are dead as hell. I go get 2 more under warranty, 2 days later I let is sit for 3 days while waiting on Airdog to get here and again dead as hell. Sometimes when I turn the key on the WTS light will come on and the glow plugs will not, and the truck is plenty warm. Sometimes when I turn the key on the fuel pump will not come on. Sorry for being so long just trying to be thorough. Any and all help is greatly appreciated.
