I was wondering if anyone has had this issue. I am running the 2 bar SD OS. I have everything nailed down in the tune except for this one issue. When put in drive there is a 2-3 sec delay before engaging. It is an 05 silverado with a built 4L70, 2600 stall. I believe the computer is commanding this based on the set MAF codes. I was hoping I could tune this out. Any insight would be great.
