Hi, I am new in this, did get Efilive commercial, and have made it work with car.
-99 Camaro with Comp 216/220 cam, LS6 manifold, CAI, SLP short headers/catback MM6/3.42 Gear. Has OS 09360361 Cal 9354896.
No modifications in ECM, work fine with stock tune exept cold runs but lowend torq vague. I am upgrading with ported LS6 243 Heads and question is:
Should I uppgrade to -02 F-body OS or -02 LS6 OS is ETC problem? or directly to some of custom OS? What are Pros/Cons. Advice is really appreciated Juhani
