I have a tripple dog with v2.3.9, none of the "Larry" programs. Am I better off going to the latest (2.4.x), or is there a better program to go with?

 

What year is your truck?

 

2003 305hp model

 

On my truck, the earlier versions (2.3.7, 2.3.9)seemed to run better. My truck seemed slower with the newer 2.4.1,or 2.4.3. The dyno may have told a different story, but as far as seat of the pants go, I liked the earlier ones.
