I installed my MiniMaxx tuner 1/2 my exhaust (was shorted 1 pipe) and a full EGR delete kit.

It seems teh egr was a success. I installed the elbow as well as the normal block offs. I started the truck with just the downpipe on to burp the coolant.

Reving the engine, I can hear the turbo spooling up, but no boost regeresting until late. At 3500rpm it shows 4lbs on my guage as well as the H&S.

Are they using the same thing to measure? Could I have left a vacc line off or something relevant unplugged. I looked around and the only thing I see are 2 plugs that used to go into the now deleted egr.

I cant run it on the street to test it out until the rest of my exhaust comes in.

Any advice is appreciated. Where is the probe/sensor that measures the boost?

 

Ok watching a few Youtube vids, I know I left the vacc line off the bottom of the battery box. Im hoping its that simple.....Ill find out Fri.

 

Are you reving the engine in park?

 

Yes, I still have the tailpoe hanging.

 

I don't know about the 6.4 but I seem to recall my 03 6.0 would not make much of any boost just revving it in park. Try putting it in gear and put the brakes on and give it some throttle.

 

Ok got it fixed. The EGR delete kit came with a new coupling and clamps for the elbow in the kit. I figured the factory ones were better so I left the factory stuff on.

Well the factory coupling has a ridge to secure it on the int. pipe. The new elbow that eliminates the EGR is on a bit of an angle that keeps that ridge from eating properly. I crushed the ridge with the clamps.

Today I cleaned the connections there and at the motor with denatured alcohol and used hairspray as suggested for lube and reinstalled. I used the coupling and clamps that came in the kit this time.
