Default throttle body

What horsepower gain would I see with stock intake coupled to a bigger throttle body? Would I see less fuel consumption? Feel free to tell me all about it.

Generally anything that increases the power output of an engine will also result in a DECREASE in fuel economy (assuming the engine is properly tuned) In order for an engine to put out more power it simply has to use more fuel.

Exhaust is a better way to go for the time being. Once you've opened things up (from the exhaust manifold on back), then it makes more sense to get a throttle body.

Many of your mods, including your intake, will actually increase your gas mileage. But, this only works if you aren't mashing your right foot all the time. As Wolfman pointed out, performance is a trade off for economy. Hard acceleration will use more gas and ultimately lower your MPG.

I put a bigger throttle body on the one sps sells and I found the horsepower increased dramaticly. I also was told by 2 big exhaust dealers here in Ontario that changing just the exhaust doesn`t do much becauseof all the bends in the pipes. Unless you modify the path of the pipe. They said the straight thru low restriction muffler does alot and it does from experience.
Also changing the air intake and the the throttle body really makes a differnce.
I didn`t find much difference in mileage from one to the other but a big differennce in performance.

I changed my throttle body and exhaust all at the same time. It was a huge difference. Also my gas mileage went up too. I easily get 33mpg with my automatic with lots of freeway driving. Before the change it was at about 30mpg. When I changed all that stuff I was ready to accept the fact my mileage would go down, but it went up. It is a nice bonus.
