Question, Does a tuner just turn off MDS, or does it also delete the diagnostic tests that sense the MDS Solonoids?
If it just turns them off, you would get a check engine if you remove the electronic parts?
MDS delete is different than MDS disable(which most tuners do) So a Custom tune may be needed if the lifters are replaced and the solonoids remove and plugged.
Im pretty sure Diablo just turns them off, not deleting the tests.
Anyone know for sure, someone thats done it.
