Let me start off I've searched, I've read and am just a lil confused. so I'm asking for help.
Ok i'll admit i'm a little green on this, i have efi live V1 and will be using the 0411 pcm (02 2500 6.0 express van)
I'm building a lq9 block (yes flat tops i wish they were dished) throwing a M1 procharger on it and have the LSr comp 293LCB HR16 ( http://www.compcams.com/Cam_Specs/Ca...csid=1421&sb=0 ) 243/259 .624/.624 on 116lsa straight up with 317's and flat tops (what i had laying around) and 43/lb injectors
backed by a t56, but my harness is for an auto that i will modify when it gets installed.
I need help on base tune for this, something i can start the car on and break the motor in on the street, i am not planning on feeding the motor with the blower to break the engine in.
should i start with a 6.0 tune and modify it for a m6 or start with a 5.7 m6 tune and modify it for a 6.0???
I've heard of problems from guys swapping auto to m6's with the plugs running way hot (from timing) cause the car always thinks it's in neutral.
any advice will be appreciated.
