I recently purchased a 2015 2500 HD, it feels really sluggish compared to my 2011 2500 I had even though it's the same engine and transmission it just feels way less responsive and heavy, I'm very green at tuning but I have done stuff on my '0411 LS swapped S10, I downloaded this PCM and to say I'm lost is an understatement, any of the knowledgeable people on here that have done stuff to these trucks willing to make a couple of bucks and help me out? It's just a stock truck but want to get rid of some of the restrictions and tighten up the shifting a bit as well as power enrichment
