6.5 Turbo, Turbo issue question
I have a 98 with 6.5l turbo and I have noticed lately when I am on the interstate it feels like the turbo is being bypassed. At about 70mph the turbo will spool up real fast then die then sppol up and die this will happen 4-5 times in about 15-30 seconds. When I step on it just feels like the turbo is not there. I did check the wast gate and it is not stuck and moves freely. The vacuum pump is working at and idle at least and easily works the wastgate. Is the a map sensor that is acting up or at higher rpms does the vacuum pump start to fall off? Any advise guys?
