My 6.0 build

Greg if there was a leak before the MAP sensor wouldn't it not pick up boost on the CTS? Where does it usually leak from. I was told if its picking up boost electronically it isn't leaking but honestly don't know.

You are correct, if you are seeing the sensor max out on the cts than you are good. Sometimes the map sensor is bad, sometimes it leaks from the rubber hose, they typically get dry rotted and crack.

Josh@DirtyDiesels · Mar 25, 2013

Yeah the sensor maxes like 33ish usually on the cts. I really feel like if it was a boost leak it would be very smokey.

this was with the 66 and Eric's full fuel tune. also on a loaded dyno. Not smokey at all...

Really looks like a fueling issue to me just like its not holding icp.

It limps itself in that video. You can hear a change in tone of the motor/exhaust note once you see that puff of smoke. And good lord does it take forever to rev itself out.

You got an issue that is underlying somewhere. Its not fueling like it should. Tuning doesnt seem like its an issue either.

rear abs sensor was bad that day. No speedo on dyno. Think this was affecting things somehow. The runs yesterday at spring fling abs sensor was all good everything working properly. Here is the first run from yesterday. No brake spooling in this one.

still sounds like it isnt reving all that fast like it should be. Is that in overdrive? I'd like to see a shot of the speedo from a 0-100.

I agree. definitely not revving fast enough. yes that is in overdrive, no brake spooling that run. 0-100 is tough right now with the wet roads... Maybe this week I can try.

Because I'd rather wait until Craig can build me a stainless setup. The banks was on the truck when I got it... Clearly why this truck makes power. It's pretty extreme LOL

ill make you one in stainless if you like. havent done it yet but shouldnt be too big a deal.

We might be doing some intake manifold stuff too so probably going to wait. Shoot me a pm though.

Quick video of ICP voltage cruising on the highway then laying into it hard. Holds pretty well. http://youtu.be/whqKbR31gm0

Dam man my truck goes to 2.2 volts on XtremeX half to WOT at half im at 45psi has an aux sensor on the edge. My fuel pressure is dropping from 50 to 32 could this affect the icp? Running 225/100 64/71/94 new hpop has 100 miles and all the updated stuuvies stand pipes. Oil rails in the back arent leaking.

Josh@DirtyDiesels · Apr 20, 2013

hmm wonder why it doesn't hold ICP... Mine seems to hold very well. New pump with about 5k on it. I don't believe fuel pressure would affect ICP at all. you definitely need to change your fueling setup if it's dropping like that. My a1000 setup is set at 65psi and NEVER moves

BlueWaffle · Apr 20, 2013

doesn't matter if the pump is new...95% of the time, the OEM doesn't have enough volume to deliver full icp with 225 and a full fuel tune.

Agreed. Honestly don't know how mine holds ICP. Maybe my "full fuel" tunes are actually pulling fuel. These mysteries confuse me

Theres no upgrade pumps except the 03-04 setup right? Or twin hpop. Yea im going to put an a1000 or magnafuel after the airdog hopefully that will do it but im reading off the regator on the rr system

Correct on the 03-04 pumps. Waiting patiently for diesel site 05+ pump...
