Or can flexfuel adjust for such mods?

?? How so? That won't lean it out anywhere near enough to cause any sort of kr.

Yea, I've heard mixed reviews about these flowmasters (dronemasters), but so far I've been digging mine. Curious about the power benefits of a different one though.

I'll get a startup vid, and a second gear pull in the next few days, and post it here.

Excellent. Very respectable numbers for the mods you have. You'll be able to recoup some small cost selling that superchips handheld when you tune for your cam. Should be a fun truck.

As mentioned above... your heads are about as good as it gets for your trim without stepping off into aftermarket ported units.

Your intake manifold is decent. The next stop would be a FAST, but that really depends on how much money you want to spend.

Being a DD... I'd get the cam in, get a good tune under it, get your gears in, stall it (within reason), and put a 100 shot on it for those lonely nights.

...then turbo, built trans, and buy another daily. <----inevitably what I end up doing.

I've got a buddy here that's pushing me to do exactly this. That's a little outside the realm of what I'd like to do with this truck, for now. Just want a fun truck to drive around.

Still not sure about which stall or what rpm though.
