The general concensus that I have seen due to this question being asked 86 other times???? Is that if your truck is stock the HO pump should work and give you a few extra ponies, but if you modify much at all you'll have issues. The ECM's have a different program, the injectors are different and the pump is different. The turbos are HX35's regardless of HO or SO as long as it's standard transmission, yours is a HY35 I believe. This information is what I took away from reading previous posts on the subject, at one time I thought my pump was going out and found a super deal on a HO pump from a motor that got hot. In the end I decided I wasn't going to take the chance of spending the money on a "maybe it might work". Besides that someday when I win the lottery I don't want to have to change it again so I can really bomb the truck.
