hey guys i got a 03 250 6.0 with 260k miles, egr delete, oil cooler update, stock head gaskets and bolts ive added a stage 1 turbo, new injectors stock size, 58v ficm and a cold air my problem has been there since before i added all this, the problem is there is a dead spot in my pedal where it builds no boost no power it will barely get over 30mph. cold start is fine at idle hpop hold 870 irp at 30, when it reaches op temp pressure falls to 630 irp at 26, warm start is fine too no long crank at all, wot hpop will hit 3300psi but it has to down shift to get that and max boost of 22psi. ive replaced the map, mass. ebp and cleaned the tube. and changed the icp, also while at idle i will randomly lose a cylinder for about 5-10 secs then it will smooth back out and idle fine, turbo is pretty quite too compared to other 6.0s ive heard. fass fuel pump 125ghp on it holds 70 psi with blue spring. anything adivce would be great!!
