phat shaft 62 turbo boost?

[ScottHerman]

i have a new phat shaft 62 turbo. i have the edge attitude with juice. i am only getting up to 38 pounds of boost according to my juice monitor. it is supposed to make up to 50 pounds of boost. i've tried all 5 settings. i have a volant cold air ram intake and a ne wfree flow exaust?today i put my juice on level 5 and my engine light came on. my rpm says it was up to 3221 rpms. it finnally turn off after i turned it off for a while. did it come on because i over revved my motor?

You will have to stack a programer or a pressure box with it to get those numbers.

Is the Truck a Auto or manual.

There is another thread right now discussing the juice w/attitude and no one seems to be seeing anything higher than 38lb on the attitude. Even guys with sps 66, EZ and TST. I bet you are actually getting more boost than the attitude shows. How about seat of the pants, does it feel like it makes more power?

From what I have been reading. . the problem is that the Attitude reads boost from the MAP sensor which is only good to 38-40 lbs. Installing a boost gauge to read actual pressure may show you are actually getting much more.



Just curious. . what year truck did you put the 62 on?

my truck is an 05 610. it is an automatic. the turbo has made a difference. i had the juice and attitude with a new intake and exaust,in setting numder three i kept getting my 0-60 times at 7. 6 seconds. i then added the 62 turbo and took a reading in setting number 3 again. i spun the tires a little and did 0-60 in 8 seconds. i then looked back in my records and saw i had 80 backdown. i figure my torque converter must have slipped so i then tried it again. i went 75% til i was rolling then hammered it and got a 7. 2 second run.

My truck shows the same 38-39psi but I have checked with a mechanical gauge and it shows 50psi. It is because the boostmap sensor that the atitude / box uses to read boost, maxs out at the 38-39psi range.
