so i put in a boost and egt guages, my boost guage fluctuated a few psi under load any only under load or getting on it, it will go from like 20 to 23psi or 10 to 13psi bouncingh back and forth, im tesed the line i ran for lraks there are none, has any one had any problem like this, not sure if its just the waste gate opening and closing or what, i havent got a change to pressure test the entire intake system from the turbo to the engine. any thing helps. it may just be a crappy guage i got, my egt guage already started to tweek out on me.

 

I'd be suspect on the gage personaly.
