Engine/Transmission (1998.5 - 2002) Boost readings dont jive w/Adrenaline

[EBung]

Installed adranaline yesterday and gauge says 10lbs and Adrenaline says 6lbs. So does this mean my MAP is junk? Truck has 63,000 miles and has had more than stock boost put to it at least half that.

boost

Mine is off about 5psi the other way, and my map is fairly new. My egt's with the Adrenaline is about 75 degrees higher than my gauge... ... ..... I'm just keepin' an eye on it for now... ... ... ..... bp

I don't have the adrenaline but have the Xilliraider 2 and have noticed my engine coolant temp runs about ten degrees cooler on the pod than the actual on the gauge. Called Quadzilla and they didn't seem to know why. I did have a ground problem before and that messed up all my readings. That could be something to check. Good luck kh

I think with elec vs. mech guages and age and different manufacturing tolerance of each, there is bound to be variance. I had a 200* diff from dipricol to isspro pyro and I had a cyberdyne read 16psi ,a mech (mr gasket)read 15psi, and the Quad reads 14-15,@ the same fuel pressure port!

Yea, figured there would be a difference, I set the wastegate according to the Addrenaline boost readings!

To be certain what reading is accurate, use a boost leak test (do NOT start engine) and the input pressure should be the same reading as the guage.
