Does Black Bear do live tunes? I'd get down there to him ASAP and see if that wakes the engine up some. As much weight as you're pulling a converter is going to help tremendously. You probably won't need much more than a 3000 rpm stall. If you don't pull heavy trailers often I'd go with a 9.5" converter rther than an 11" since it will help you rev quicker. If this is a daily commuter truck then I'd go probably around 2600 on the stall but still stick with the 9.5" for faster reving.

I'm not sure what exactly a live tune is. He ships me a cable that I hook to my laptop and plug into my OBD port (i think thats what its called) then the program on the laptop records me driving. i sent that file to him, he collects the data and then puts the tune on a PCM. He sends me that PCM and i put it in my truck. As for the stall. Everyone is telling me to get a stall. How much do they run? Hard to install? What size stall? I want to get a super charger later on, will the new stall work with that?
That is pretty much a live tune.
As for a converter, I would find out where your engine starts making HP, or call your cam supplier, and order a converter 200 RPM higher. If its supposed to start building HP/TQ at 2400 get a 2600 RPM stall. I always suggest a 9.5" Vigilante converter for racers. 11" converters are for offroaders and guys that tow a lot. A stall is easy to swap out, just be careful and have a friend handy to help. Stalls run from $200 to $1000 depending on brand and options. Be sure to get a 3 or 5 disc stall to handle the torque of a supercharger.

+1 to that. You should be happy with a 2600 stall with your mods--it has great driveability. I would recommend getting that tune in soon. With a stock converter, it will be a dog out of the hole. If you've got any questions when doing the install--ask a few questions on the Live Tech Help on the main forum screen.

for what it's worth, my stock 5.3L made peak torque at 4000RPM just like the factory rating. A longer duration camshaft is likely to move that RPM range up a bit.
Cable for the tune was sent today. I'll probably have it in 2 days. I'll have the tune by beginning of next week. i also ordered a 160 T-stat. 2600 stall will be my next mod.
