I have a 2001 with a 5.9l gas, here's what I've done so far. Mopar single plain high rise intake, mild cam, 1.7 ratio roller rockers (upgraded from the 1.5 standard rocker arms) big gulp 1000 cfm holly throttle body, pace setter headers, single 3" exhaust system, 4.56 ring and pinions (upgraded from the 3.55's) 5" lift with 35" tires, now here is what I am curious about. I've done a lot of research on power programmer's but am having a hard time deciding on which route to take, anyone have a good programmer that they have been completely happy with?

 

Most people go SCT by either Flyin' Ryan or Hemifever. I have had good luck with hemifever but never heard anything bad about ryan either.

 

Custom tune from Hemifever is going to be your best bet.

 

Or Flyin' Ryan. I would suggest talking to both before deciding.

 

He has some mods in there that are going to require a custom tune. Flyin' Ryan is now wanting to actually lay hands on the truck for that, Hemifever will still do it via email.

 

Ryan had a high enough demand for our rigs that he brought back email tunes. Last I checked he was updating his website to reflect that.

 

That's good to hear. (read?? whatever. )
