Topic says it all... Chevrolet 04 Crew Cab Dually, 4x4, 6.6 turbo diesel, allison 5 speed.

Thanks in advance, VR :D

How much boost? it varies at different throttle positions/how fast you're going.. but in general, max of 27-34psi or somewhere around there..

wow.. I only get about 20-25 out of mine.

At 60 flat ground I have about 6 + or - lbs. WOT I have seen 29.6 lbs. That was with the Juice on 5 with a top speed of 97 mph.

i only get 20-25psi out of mine also. i don't know how you are getting so much

Wow!! :eek: Thats quite a bit!! Thats for a completely stock truck like mine??

When I say 27-34, thats the max it can produce, I believe. Can someone correct me if I am wrong?

It's definately variable, all depending on weather conditions/where you live, in conjunction with what other mods you've done, I've seen my turbo reach 27psi from stomping on the pedal all day under various conditions in so cal.

Mine will get to a shade over 30 with the Juice/Attitude on level three. The Attitude is set to cut back at 32 per Edge's recommendation so that may be some of why it stops there. I know that when it was set at 30, it was de-fueling quite a bit more between shifts than it does now.

I think the juice reads the boost from the computer or before the intercooler thats why some with the juice will see 29 to 30 ..If you have a guage that you tapped into the intake i think you will see from 20 to 25..This is what i saw from my experence so you guys can correct me if i am wrong...

Before I Put The Big Head On My Truck The Stock Wastegate Was Holdin 22 With Banks Turned To #1......wot Truck Unloaed....havent Tried Pulling Travel Trailer Yet As Theres Snow On The Ground Here.....damm I Wish I Lived In Cali MINE THOUGH IS AN LB7..NOT SURE IF THERES GOING TO BE A DIFF

Thanks for the info guys!! I am in shock as to how much boost this thing actually puts out... I was expecting 8 or 9 lbs. Certainly not 25!! :eek: I have a S/C Corvette and it only puts out 10 lbs... but the difference is phenominal!

VR :ro)

When I was proving to GM about my overheating I had their diagnostic board which kept track of all that stuff. While I was pulling a trailer up a hill at WOT it read 28psi. On flat ground empty 30psi.

this sounds correct from my experiences with superchargers. I think the edge reads what the turbo is making and not the amount of pressure actually at the intake..that is where the most accurate reading will be. Your turbo may make 35psi, but after going through piping and intercooler that is usually cut down 2-5psi on most setups that I have seen. My edge has read 26psi to my knowledge. the LLY's have no wastegate installed so it depends on the tuner/programmer for the boost compensation.

..and if I am wrong, please correct me.
