Hello all.Considering tuning on my 2019 L5P and have one question for now.Is it necessary to buy a HP tuners tcm when using their engine ecm.The reason I ask is I'm not looking for any torque increase from this truck, the power if fine,I just would like to be rid of some excess components and not have to buy d.e.f.I don't see what I have to gain from buying a tunable t.c.m I don't need increased clutch pressure, modified shift points, modified t.c lockup etc.I think the vendor I talked to is b.s ing me that I need a cracked tcm with tunes.
