I had 2 cummins rams before and they were drag racers off the line. this one has 98k miles and with the after market piping and such i was wondering if i might have a boost leak, or if this is normal for these trucks? are they normally pretty laggy? mine really boosts around 3k with some coming on around 2.5 - which seems high to me. also, I've heard these models have notorious head gasket issues. anyone know what the symptoms are to look for? with a gas engine I could do a compression test, but not sure with a diesel. thanks for any info guys !
