One way to check the map sensor would be to hook onto a trailer and do a performance test. This test is best done with a load, like a trailer.



Run through the gears for a mile and see what your time is.

Now run through the gears for a mile again only this time unhook the map sensor and see what your time is.



If the performance times are the same or real close than your map sensor is o. k. , if the times are way off then the map sensor is the culprit.



This test will set a code.

I did this test with mine just I didn't pull a trailer. When I pull the map sensor its a total dog. Is this normal or?

can't wait for the answer!

my truck is doing the same thing. i posted a subject in competition forum about getting beat by a guy with only a drag comp and i got beat by a guy with only a comp. something doesn't make sense. can you have an internally blown headgasket and if so how can you check?

The only thing i have not done yet is replaced the vp44 and the headgasket!!!

How did you ground?

Just a thought here,



How did you ground your power max 3? Don't those use the BC pump cover and for ground it tells you to use the black with brown tracer? Only reason I ask is this is what I accidently did with my comp and I am wondering if I screwed up the VP this way.

What are you comparing the turbo to? If you are comparing it to the 35 that your truck came with it will be considerally worse on take off. That one of the down falls with the bigger turbos that we all have come to deal with. Alot of companies are working on ways to make it better, but I still feel they are alot worse than stock turbos.

Yeah I thought mine was lag too when I installed the K45. Then I switched back to the HY35 and still have the problem. It's not the turbo. It's something else. I am starting to think this is a VP issue.

Mine was having simliar problems... turned out to be a head gasket... . internally blown... no external leaks..... Have you changed the oil? check'd the antifreeze??

So how can I tell for sure? Oil looks fine. How would I tell looking at the antifreeze? Should it be milky from oil mixture?



Thanks for the help.

I checked my dip stick... & it looked fine, but when I took off the oil fill there was the clue. . milky residue... . If if styll looks fine, try taking off the vlave cover, that should tell you right away.



Also look for abnomal smoke(blue or white).



I dont want to scare anyone, it probally isnt the cause, but one could never be to cautious.

Thanks for the direction. I'll check it out tonight. I have seen some white smoke but thought it was just fuel not burning completly. Thanks again,

compression check?

So after looking and looking for milky residue I came up with nothing. A gasser buddy of mine said if I have a blown head gasket that a compression test will surely show it. Is this true?



If so what tool do I need to get my hands on to run a compression test?

 

[CRegal]

You would need to get a leak down tester, not sure if a regular gasser one would work or not. They normally plug into the spark plug holes, then you turn over the engine & read the compression.



I am not sure where you would take the compression check at on a diesel, but I am sure there is a tool made to do this. Yes that should also tell you MIGHT have a blown headgasket.



BUT from what your telling me, I wouldnt think so. It would be pretty apparent in your valve train if you had toasted a headgasket. I would keep checking it now & again, just to make sure. If you do have a leak, it will eventually get worse.



It's alot of work to pull the head off just to look. I wouldnt do it unless you knew for sure.



I would start to look at other things in the intrim.

Compression tester?

What would be a good or correct compression tester to use on a CTD 24 valver? Can anyone tell me what is the best valve lash on a 24 valve is? I know what they call for but does anyone have a better lash they are running?



Oo. Oo.

I just remembered something...

Back in the 70's my brother came to me with a problem. His son had used his car, a 1978 Fury III, and had been powerbraking to make it do a burnout. After that, the car ran much like you have described your truck running. It turned out there had been a series of failures because some torque converters had not been properly brazed. If the vehicle was loaded heavily, or powerbraked, the internal fins could collapse, turning a torque converter into a simple fluid coupling. His engine ran fine, but the car would barely move unless he floored it. It felt like the car was towing a very big trailer and was a really radical performance change.



Maybe it's time for one of those fancy new high performance torque converters.

Turned out to be my VP had died. I have been running a new VP for a few months now and the problem is gone.
