I have a 2003 truck (mods in signature), and I just upgraded my Smarty Jr to the newest software 5.11. Does anyone have the same setup and what timing and TM are you running?

I am currently on SW3, Tm 2 and Timing 3


Thanks,
Kerry

 

I run smarty Jr on SW3 and timing on default and the torque on the least responsive besides stock 4 I believe. Since you have your tranny done you should be fine for the perf setting. If you want to take full advantage of the JR add a HE351 (turbo of the newer trucks). I did this and she hauls now. Besides the Jr the turbo has made the biggest difference. Mind you I did the exhaust and ATS manifold at the same time too. I have enough air and fuel for 450hp. Not sure if the Jr adds enough duration to get past 400hp though.

 

Is this turbo upgrade pretty easy (direct bolt in) or did it require a lot of modification to work?
What year truck did the turbo come off of and what other parts (if any) did you need to connect to your 2003

 

Do a search on HE351 turbo swap info. The thread is 17+ pages long and is the resource I used to do the swap. Pretty much direct bolt in. A few gaskets, turbo and boost elbow (optional) and away you go. To take full advantage of the turbo you will need a smarty Jr or boost fooler. I bought my turbo for $300 and 4" exhaust elbow for $25.
