turboback question

01 7.3 , do I need to retune after installing a turboback? Im we'll aware it'll optimize the mod if I do, but do I NEED to right away? (Will it run lean or anything?)

Thanks!

No you do not need any tuning to run a full exhaust

^what he said. But a chip with some good tunes will make the truck more fun to drive.

They won't add much power just by themselves, but you do not need a tune to run either. Those are the most basic mods that people do to these trucks.

AFE stage 2 advertise 112 tq (even at the flywheel) that's not shabby?! I keep hearing to stud the heads... at what point is that necessary? im assuming not at the bolt on level? or is there a boost level that its recommended at?

I have never personally tested that, but I think it's a bunch of bologna. There is no way that just switching out the intake will net you that much.

Whoever is telling you that you need head studs on a stock 7.3 is someone you shouldn't listen to. These aren't 6.0s that need them with just the basic bolt ons, 7.3s are pretty good at holding the headgaskets unless you're making an obscene amount of power and boost, and they are certainly not needed at the intake, tune, exhaust stage.

I agree with you on multiple accounts, I mean it does have a lot of displacement + boost so I can see how some would believe it but it sounds a little inflated, and I was hoping it wouldn't need studs at that point.

So what boost could I expect with a stage 2 AFE and a full 4 in turbo back (w programmer) ? approximately

intake and exhaust will add about 20 hp over stock.
the main reason for doing them is as a supporting mod for when you want to chip/program your truck.

usually can't run the stock compressor wheel over 25 psi without some major surge issues.

with a good custom tuned chip and billet compressor 30 psi is pretty easy to hit. as long as you don't have boost leaks/driver pressure leaks.
