I already have a 97 computer in it. will i need to change the idm? just looking for a more experienced opinion. Thanks
Late model 97's have 10 bolts in the intake plenums instead of 8. If you have 10 bolts holding on your intake plenum, this means you have the SuperDuty heads.
This makes it way easier to upgrade to 3" billet plenums, which might I add is an awesome upgrade, imo.
Most of the diesel performance shops don't carry 3" billet plenums for the 8 bolt style due to lack of demand.
Besides that, there really are no major differences between years and you don't need to do anything special. Your wiring harness and IDM will hook right up.
