Engine/Transmission (1998.5 - 2002) Boost seems low, Egts high????

[KKlingbeil]

I have recently put on a comp box, and am still using my superchip as well. I have stock exhaust and the stupid hy turbo. While driving at 60 mph or so, my boost is at zero and my egts pre turbo seem to stay above 700 and closer to 800 all the time. egts seems high, but i though i used to run 6 or 7 pounds of boost at road speed. Anything wrong??? I dont know... I first thought maybe i blew a intercooler boot off, but if i smash it it will still hit 35 pounds or so, but it doesn't seem to spool up that fast either. Anybody have any ideas????? BTW the wastegate is stuck shut, and dodge put a new turbo on one year ago because of stuck wastegate. Thanx in advance!

Is your air filter clogged? Those EGT's are not unreasonable for normal driving. Check your gauge. Is it mechanical or electrical? There could be something wrong with it. If you have access to a scan tool, you could compare gauge readings with MAP readings from the computer (this will not work if you have a boost fooler).



BTW, when I drive @ 60 on flat ground with no load, I only see 2-3 psi boost.

when im doing 70 or 75 im still running 0 pounds on flat with no load, my air filter was just cleaned, so its not that, and when im doing the 70 or 75, i will get up to 900 on egts, and the boost wont hardly move. I would think with the 9 cm^3 housing that it would be running 7 or 8 pounds???? seems that it was never like this, but maybe it was i dont know... I am going to try and get a scanner hooked up.

did you check for any leaks at your gage. . I had the elbow and it leaked. when I put new fittings on I gained 8 more psi. . A small leak can fool you.

Also put a better air filter. . AFE or something like that. This will help.
