I have the Juice/Attitude, Banks exhaust, and the Uni filter. The highest boost pressure the Attitude has recorded is 23psi. I've towed a 10K trailer hundreds of miles up hills, ran the 1/4 mile and just raced around empty. Does 23psi seem low?


Thanks,

23 psi is about where the waste gate opens. without messing with it you shouldn't see above 23 psi.

Thanks a64pilot. I had read others stating 26-28 psi. They must have altered there waste gates.

Depends on where you are measuring the boost at as well. Most people are not modding the wastegate due to the danger it poses to the turbo.


The attitude boost measurement won't read over 25 PSI either.

I've got hot/juice/*** and my *** shows 25.6psi of boost.It also showed the same with reg juice (before hot upgrade).

Quad 165 puts me between 26-28 with a stock wastegate.

I used to get overboost codes with my 10k trailer running up some hills with 23-25 psi running in level 2 juice. now with my attitude i can hit 26-28 and hold it there in 5th for as long as the pedal is down. does this mean that my wastegate is not operating properly. i have never altered it. also these numbers were being read in 10-20 degree weather with the attitude and my autometer boost gauge reading this.

My wastegate is stock and the highest I have seen is 24.2 pounds of boost running J/A level 3. I figure this is about normal. Sooner or later I bet I will hit 25, maybe more. --SS

HJAT level 5 + stock waste gate = 26psi boost on the dyno, monitored at the waste gate line.


HJAT level 5 + Banks waste gate actuator adjusted 12 turns = 31.0


Load test on the dyno all same as above = 37.0 http://www.dieselplace.com/forum/smileys/Shocked.gif

OK maybe I should have said 23 ish. There of course are manufacturing tolerences at work here. EX. mine stock pulls around 24 with a TST comp box. With TST's sense line installed it pulls around 32. The only change being the modified sense line.

I just put on an Attitude and it seems to read faster and a bit higher than my Isspro boost gauge (tied into the wastegate hose). Mine tops at at 23-24 on the Isspro and maybe a pound or two higher on the 'tude. Running the interstate on cruise, my Isspro cycles between 4 and 6 and the Attitude says 6 to 7.

I have about the same findings as Idle_Chatter with the same gauges (tapped into wastegate hose).


My Attitude also registers a 25.6psi for the max recorded. I'll have to do a reset to see if that was already in there from the factory.

I hit over 23psi easily with the Juice on level 0, flat highway, empty, downshifted to 5th and put it to the floor (~60mph). I'll try level 5 today and see what it hits.http://www.dieselplace.com/forum/smileys/Cool.gif

28 PSIG Post CAC reading WOT in 4th gear

My Attitude displayed 25.6PSI WOT in 5th gear pulling a 17ft. boat today, didn't look like it was about to go any higher than that.
