Pros and Cons of TB Mod

I know that there will be a power increase but where, I use my 7 as a daily driver / street racer, and am concerned with low end power and gas milage, will this mod make the engine run any better? or will it just help it produce more power. I'd apprecaite any input on this subject thanks

It really doesn't produce significant amounts of power.&nbsp It does reduce an unnecessary obstruction in the throttle body, especially at high RPMs.

An obvious downside is that you gotta watch it with the throttle under 3kRPM or so.&nbsp Abrupt throttle changes from cruising to WOT will award you with a lean stumble due to the throttle plates opening so abruptly at low intake velocities - this is more a drivability problem.

how about modding it a bit further than normal?

so it looks like this for example

that should get things flowing a lot better

is your car turbo or not?

Its one of the GeoCrap things, you have to cut-n-paste the link into your browser, they don't allow direct clicking

Would you still have this stumble on a turbo charged car? I'm doing the fuel system upgrade after the holidays....pump injectors and an AFC later on. IF the problem still does persist i should be able to tune it out ???? I need to know...thanks

The mod was originally for just the turbo cars; I really don't recommend them on NA engines, but people have figured out how to adapt the mod to them.

I have done the TB mod and it really did not give me much power for my 87 sport. at least not peak power but it seems to have smoothed out the powerband a little and in the higher rpms it has made it pull a little harder.
not much but a little

I would still say it is worth it
cheap mod
easy to do
