Hey all I just bought DHP from a guy on W-Body.. I'd be extremely thankful if anyone can direct me where to read/watch videos anything to get some knowledge about modifying my PCM. I have a 1997 GTP if that matters basically stock my MAIN reason for purchasing DHP is fuel economy and some other stuff I have a ZZP 1.0 PCM which was edited by a guy I know he said he put the fuel tables from 04+ and that would help and I do believe him BUT I also know he didn't take time to go over everything and you can't have a real tune on 1 test. So like I said if anyone can help it would be soooo greatly appreciated! Thanks! :th_thumb-up:
 


Why would he utilise 04 tables...aren't 04+ return less? Which means it'll be irrelevant on a system with a return
 
I bet the guy meant timing tables. Most use the 05 GTP timing tables and then drop down the cruise section based on knock etc.
