Diane,
Would you please verify if Jody has tested the 99~03 7.3 with this CPS, IH1821720C99?
Will any changes be required to my tunes to accommodate this version?
60tow, 80tow, 80econ, 120
Thanks

The one ending in C99 is the replacement for the C93. There were no changes in performance between the 2, so you do not need new tunes.

Sorry, I thought this CPS was for the earlier year psd and (edit-advanced not retarded) the timing by 2 degrees when used in a 99~03.

The blue one retards the timing. It came from an in-line 6 engine and it not recommend by Jody to run in our trucks due to tests he performed over 3 years ago.

The C99 superceeded the C93 one. This came straight from an IH dealer. Their are no more C93's available. Soon, very soon their will be no more C99's either.
