How much stress can the 4.0 drive shaft take??

Thats what I hear as well at high speeds. I'd upgrade if I were going FI. If you're getting tlok and gears maybe think of just swapping a take off GT rear axle so you don't have to go through any hassles of a bad install. If the money isn't tight you could do the aluminum drive shaft at the same time. As far as the CAI go for a cai/tuner combo.

i heard they break at excess of 115mph, ive pushed it past that and been fine, as for tq? im not sure, as stated, you should just do a rear axle swap, and get a new driveshaft from shaftmasters, they are lightweight and lose rotating mass, which means its easier to transfer power from your flywheel to your wheels.

But replacing the driveshaft with a one piece aluminum would be beneficial even if you're not going F/I. It's not the most cost-effective mod but it's insurance against the driveshaft grenading at high speeds and you'll pick up a few hp from the lighter weight. Also, if you put some better tires and swap the driveshaft you'd be safe to remove the limiter and top it out
