I, myself, shift around 3500 in every gear. I've got 33's with the stock 4.10's. I live in the mountains, so there are a couple local hills that I have to keep it revved at 3500 in 3rd to get up the hill. I do occasionally hit 4k though so I can shift into 4th for a few hundred feet, just to pop it back into 3rd at 2800 and catch back up to 3500 and possibly repeat the same process.

 

When i go to Hesperia, CA there is a very steep incline on the I-15 NB and i usually can keep it in 4th gear @ 3000 rpm and stay around 60mph. I can kickdown to 3rd and speed up to 75mph @ 4500 rpm. I can't keep it in OD because it will bog down the hill is really steep. On leveled highways i can easily redline and make it to 90mph in about 14 sec. I usually only go past 3000 rpm when i need to pass someone on the highway.

 

To get going in 1st with any decent accelaration you have to pretty much dump the clutch at 2500-3k. If you dont let the 3v warm up in the cold in runs like a complete dog bucking and surging especially in 3rd around 2500rpm it surges like 5 times in a row and it feels like its going to die. then once it warms up runs like a champ
