Hey folks, I have a question on the after market tuning vs. the plug in programers. Plainly putting it what would be better for me? Right now I'm running a custom cia w/a K&N, I have installed good plugs and wires and running a single 3" into a dual 2 1/4 out flowmaster 70 series( had a 40 on it and couldn't take it ). After putting on the cat back I have seen my gas mileage drop ( its been on for a while so I'm used to the sound now) and my driving habits are back to normal. I have heard that after letting the 5.3 breath better I might need to do some work to the pcm so that it notices the changes. Would it benifit me to buy a plug in or get a new pcm? some time here in the future I am going to put on fans also and was also told that the plug ins' won't work on that...... Does anyone have opinions because I have no idea

 

Get the Edit. Its going to help your truck out way more than any hand held can. You should take advantage of the $200 mail order tune right now

 

Where/who is the edit through? I might be missing something as usual. Are the pcms' from nelson good?

 

The mail order tune is thru Texas Speed. I haven't heard very much about them so I dont know how good they are. I have a Nelson tune and its working out badass for me. I lost 5 tenths switching from a hand held to Nelsons tune. I'm sure a few more guys will come on here and tell you about there experiences with Nelson.

 

Nelson tunes rock, look at my mods not much but enough to get me low 14's and after next weekend mid 13's

 

Nelson tune allows me to break traction when I hit WOT at 30MPH. Nelson is awesome!
