I just installed a TRD intake, then unhooked sound tube piece halfway and the rest left on the firewall. Just zip tied the remaining to stock brace/strut and plugged. Plugged from the outside.

Has anyone actually verified any difference in idle or air/fuel mixture now that there is more air available for the engine now that the tube is deleted? The last thing I would want to do is require a tune just because of deleting it. Maybe I'm thinking too far into it, but from the reading that I've done, our engines are rather picky. More air without more fuel and running lean could have long term effects?

So here's my story. My friend's and I had issues with the stock air intake. We'd stall easily and shifting 1-3rd was felt too much. My friends include me driving manual for say 5 solid years, my father for 20years, 2 friends who have been for 2yrs and so on.
We all noticed it so we test drove 2-3 other's to check and sure thing, there it was. We easily stalled.
Almost a year later (now) with the TRD intake (sound tube deleted) I never stall. My father argues there was a leak somewhere on the sound tube. I'm not sure about that. Car drives better, mpg in town is 2mpg less and in hwy 2 more. Maybe that is just me.
p.s. the only tune you need is to unplug battery for 5min and let car idle for a good 5min by itself. You'll notice the car adjusting for about 200miles. I noticed it for 500...
