E series boost and egt

[rpm-inc]

I got my gauges installed. 1st and 2nd gear i get 12lbs. 3rd gear it drops to 9 and then climbs to 12-13. EGT goes to a hair over 1000. Is this typical?? This is stock how it came from the factory. I am going to see if I can get my Walker BTM installed today as well as order a dp tuner!

Any input?? Got the walker muffler installed and now get another pound of boost and the egt's dropped about 100 degrees. I redid the tee at the MAP sensor to make sure it wasn't leaking. Same numbers. I should be seeing 15-18 psi?

E-series doesn't have an Intercooler as far as I know. That could be the reason for the low boost numbers and the higher than normal EGTs. I am by no means a 6.0 expert...or an E-series expert...but that's my experiance. Have you tried to tighten the intake hoses from the turbo to where it enters the engine? Also, try to torque down the manifold up pipes to the exhaust side of the turbo. That's about all I can suggest.

Do you have a 6.0 engine or a 7.3 My 7.3 reads 0 at idle or no load situ. wen i pull my rv (5th Wheel) 36' i get about 4 psi boost on the road slight up hill gets about 5 to 8 # .Egt is about 700 in cruse 8/900 under slight loads,(up slight rises on the interstate) ,with the trailer on 1200 in the lower gears.. i run about 21/2200RPM 5th gear. cruse set Hope this helps you Bill

No intercooler, 7.3. I think my egt's are ok. Looking for reasons why my boost is lower than normal. Max maybe 14 psi. Stock with the Walker BTM.

You should be seeing about 18-ish with out a tuner...though w/out the IC....it could be lowering your boost numbers.

Yep, no intercooler, but the last of the 7.3's. But having no intercooler would increase boost, no?

Your boost #'s are right on target, 0 at idle or NO load should flick up about 5 in the lower gears stead y running on hte interstate should b about 4 psi... If you are concerned about boost check all the fittings from the otput of the turbo 2 where it goes into the manafolds on the heads..ie there are rubber hoses Short ones going to the headfrom the Y the turbo output will have one or it could have a clamp going the metal Y pipe. That is how mine is set up. Hope htis clears up 4 u. Your boost s fine Bill

I am only concerned about the boost because I am afraid something may be wrong. The van runs fine.

I talked to Jody @ DP today, and he also said the boost is low. I have the gauge hooked up at the MAP sensor, and I am 99% sure the connections are fine and there are no kinks in the line going to the gauge.

Lorch-I did look at all that, but I will again to be sure.

Installed a new fuel filter today, and the van seems to run stronger. Now get 14 lbs and it only drops to 11 at the 2-3 shift. But at 14 lbs the needle starts fluctuating rapidly???

I took off the intake tube to the turbo and the wheel has no play that I can feel.

Sorry for all the questions. I am getting my dp tuner ordered and I want to make sure everything is ok!
