HELP trying to get my 5.7 swap to run w/o transponder!?!?!

The easiest option is to get a computer from a vehicle without SKIM.

Another option is to get the SKIM disabled. According to their website B & G performance will do it for $230

Another option would be to wire in a skim module with a matching transponder and key.

Here's an old thread on the topic as well.
