    P0121 DTS code --- TPS issue

    I have done the search and reviewed several threads on this matter. I do have a big cam 244/248 LSA 112 which is why this code is generated (at least most tuners are saying this). The min MAP is 55 while the max MAP is 65 in the diagnostic portion of my tuner. What do I do with these values to kill off this error code? Threads have suggested min = 0, max= 100,,, is that reasonable?

    Also, could someone explain the significance of the min MAP value and the max MAP value,,, how do they come into play here?

    I have had that table disturb proper operation of an A4s in 98s before and disabling by setting the values to 0-100 helped that issue, but I've never seen it have any other impact before, or even heard of it. It's about a window of expected operation that is seriously shifted by large cams.
