New here and im hoping im doing this right. Have a 2007 5.3L silverado that im debating on what to do next as far as upgrades. You can see my signature and here is a link to the dyno pull i recorded.
I guess my thoughts as what to do next are: 4.10 gears, tranny upgrade, JET throttle body. What are yall thoughts on what to do next? Thanks in advance.

Cam and a stock MAF.

Keep your stock TB and forget the jet. Go with a cam and a good converter and that will really wake it up

Why do you say stock MAF? The jet high flow was on during the tune. Also cam before gears?

A stock MAF is better than a jet maf.

You can do gears whenever you like, doesn't really matter.

Also just a fair warning, if your truck has a stock aluminum driveshaft I highly suggest you do not go over 100mph. They are known to explode above those speeds.
