How exactly does the quadzilla adrenaline read boost and what should my boost be? The app on my phones reading like 19 max. I’m not hearing any boost leaks though.

Got a boost gauge?

 

I'm going to ask did you install a boost elbow on the wastegate line? If not the wastegate will open at 19 PSI.

 

Also Quadzilla only reads the MAP sensor like on my truck the Quadzilla report my max boost is 67-69 PSI but actually it only 47-49 PSI on the gauge.

I do not have a boost gauge yet. I plan on getting one within the next week or two. I do not have a boost elbow on the wastegate line either.   Yes I’m just going off what the quadzilla gets from the MAP sensor but the highest it’s ever said was 24psi and that’s when I was messing with the tuning for the first time and had the fueling all the way up. Where would I install a boost gauge? 

Boost fro 0-16 psi is read from the ecm output,  above 16 psi is the ecm output plus sensor output.  

 

I am guessing since you don't have a boost elbow your waste gate is opening and bleeding pressure.

For boost connection, I like the port between 7(map sensor) and 10 (intake air temp) or the port to the left of the map.

 

I think it is 3/4" npt  plug in there.  Just get an adapter from 3/4" to whatever fitting your boost gauge tubing is (usually 1/8 or 1/4 npt)

Correct... 3/4 to 1/8" bushing and hook up. Exactly where I'm at.

 

Just for information... Without a quadzilla no boost fooler, just 150 HP injectors I can still build a solid 30 to 32 PSI. Fairly smoke free. No EGT's issues even WOT just above 20 PSI the power flatten out but the truck is very drivable. Be glad to get the new Quadzilla soon... Get my MPG's back... That is the only down side!
