Just so you know, the "Hellcat lifters" aren't any different than the regulars lifters after '15. I think Mopar improved the lifters when the HC came out, but the same lifter was used in all the Hemi's at the same time.
Why are you keeping the MDS? Because the cam you have has it maybe?
Yes, that is the main reason, planned on keeping the cam, well other than not 100% sure my snap on can turn off MDS without also having to pay someone to do that too.
I was under the impression that Hellcat was high performance and did not have the MDS system since any performance lifter from anyone like Melling is MDS delete.
Guess its just the usual of asking the wrong questions from the get go.
