I have a 2000 dodge Cummins modifications are edge comp hot unlock 7x14 injectors sxe366 fass 150. Lately I have been having this issue with high egts and boost gauge fluttering. I use to only hit 1200 wot with filter and now I go past 1200 with or without a filter. And sometimes my boost gauge flutters 30-35psi and other times it smoothly goes 45-50psi. I run 17psi at idle and 8psi wot. Any help to figure out what's going on will be gladly appreciate. I already changed boost line and intake manifold gasket and checked all my boots for leaks
