Thats about all l can get,at one time my truck was getting 35 PSI,waste gate must have be stuck or a hole in the hose between Elbow and Acctuator.

--- Update to the previous post...

Can you buy that Edge Elbow as a stand alone or do you have to buy the electronics?

The one i have is a TST i believe,maybe i'm just not smart enough to get it to work? Tightening the allen screw should increase boost,Correct?

no adjustments on the edge elbow. i found it useful, as my wastegate was opening early. i have no boost fooling. if i get into the throttle it sets overboost code, but no :cel:.

Then do a test run the boost should never rise above 35 PSI. If it is the open/unscrew the allen screw a 1/8 of turn and test again... Keep doing this till you see roughly 34-35 PSI...

I looked for a DIY boost elbow and came across this Dawes Device unit. It sounds like the real deal but does anybody know if they're better than anything else?

You mean this ? http://www.kermatdi.com/servlet/-strse-176/Dawes-Device--dsh-The-Basic/Detail Its expensive and you still need boost fooling (chip) to not throw codes. Go with a vendor from here like http://www.dieselautopower.com/product_p/boostelbow.htm Hard to beat that price. If you want to make your own ..... from CF - probably $4-$6 "1/8" 90 and I drilled and tapped it and then put a allen set screw in it. If I needed more boost I would just crank it down some till it restricted the air flow to the WG. When I drilled mine I drilled straight in from the right angle so the allen would close off the incoming flow. My allen stuck out of the 90 about 1/4" when all the way in. I used blue locktite to hold it in place "

Have it screwed all the way in,only getting 20-22 PSI. Guess i'll live with that for now.

That's it. It just sounded like a good deal the way it holds all the boost till you reach the set amount but maybe the gain from that isn't enough to warrant the cost.

Are you getting that much boost with a stock truck or do you have some sort of power adder? I barely get 18 psi stock with no boost elbow.

Hmmm... Do you have...

[*]Boost fooler to keep the ECM from seeing over boost condition?

[*]Extra fuel? It takes fuel to make boost?

You could check by taking a pair of vise grips and carefully pinch the hose shut and take a test drive... If the boost rises more then your boost elbow doesn't shut enough... :rolleyes:

At one time i was getting 35 PSI,but that was on my old block

Don't have a boost fooler,just a hypertech program.

I had one of those - it was better than I thought - but seriously - sell it and upgrade to a edge comp - even second hand for like $300. You don't have to TAP the vp44 if you don't want to - it just has so much more and gives you awesome power if you do wanna tap the pump. It also has boost foolling.

If you go light on the peddle to keep your tranny+TC ok - you will even pick up 2+mpg.

Been through 3 NV5600 already,just looking to put in those RV275's and up the boost I think will be plenty for me,I'm always Hauling weight gotta watch the drivetrain. Might think about one if i could find a used for the right price.

Wow! 3 Transmissions... :stuned: Still running the same one from the factory NV4500... Edge Comp on 5x5, RV275 injectors and SouthBend Clutch been no issues here... Hauling weigh, skidding logs, etc... :rolleyes: Must be the NV4500 are bit tougher... :shrug: - :lmao2:

Sorry - didn't see your a manual. Still - the thing is you don't have to run on 5x5. And as long as you don't mash the peddle to floor - the advanced timing/fuel control at that level for trips (hauling/interstate) will net you extra mpg over the hypertech and pay for itself pretty quick. Just sell the hyper on cumminsforum and buy a secondhand edge comp for like $300. Just make sure you have EGT and tranny temp gauge. Else - buy the juice for $350-$400 and it comes with all the guages and probes you need saving you again $$

The COMP/juice will net you more BOOST + more POWER + more MPG than the RV275's - and do it all in one hit.

I like the RV275's - but the power is not hugely noticeable - maybe 30HP - thats hard to feel, the mileage varies on trucks - 0.5+mpg for me and 2.5+mpg mike ........ and the RV275's don''t do everything else - do you already have guages ??

anyway - hope that makes sense - protecting the drivetrain is always my big concern also now ...... but would think as long as you drive her like a diesel (which I am guilty of not doing) you should be fine, pick up extra power/features/monitoring + fuel savings :)

best of luck

I'll look into getting a used one for my truck,need new Injectors anyway and 275's are the same price(mine have 782K on them). I do have all the gauges short the tranny temp(have one just not installed) Look forward to Mike's pics,but I think what he considers weight and what I do are different animals.

You do understand that without Boost fooling via a box or programmer that any boost psi over i think 20psi will set off overboost code# and the ECM will defuel to overcorrect the increased boost psi.

to sum it up.. without fooling the ECM the the boost elbo will make your truck run like sh$$
