mine truck idle at 775-825 when hot,is it normal for a manual one?
i think this is a little low...

also while cruising im trying to stay between 1800-2000rpm at 70mph ,and i shift around 2100rpm,
while mashing on it i let it fly to 3000 but even there its really strong and i feel im way under the power spot
while driving but buzzing higher while cruising seem wrong to me...

 

My truck idles at 750.Idle speed isprinted on the engine data sticker on the side of the engine too. I try to shift at 1800 -2200 for normal driving, but will take it to the rev limiter 3200+ once in a while.
