Default Tacking up slack in the gas pedal

ok i did a search, sort of figured out what everyone was saying. but does any one have any pics of how thye acutally took out the slack??

Another question, before doing the bump stop mod, would you want to take out all the slack first to get a more accurate reading from the mulitmeter? B/C i know that if your under the hood and pull the throttle back it goes to the bump stop, but from the gas pedal it does not touch. That is why i am aking

Do not bump-stop it by the meter, do it by ruler to
dead center. Then verify the voltage is still proper
at closed and WOT.

TCS/ASR cars have three cable runs. Two are
adjustable and one is not. The run from pedal to
pulley cluster has to be fixed the hard way. I
used a piece of vacuum hose, a washer and a
piece of heat-shrink tubing but you could use
other things. Slit the hose lengthwise and the
washer across one side. Slip them over the bare
cable with hose against the pedal and washer
against the ball end on the cable. Slip the
heat-shrink (which is just larger than the vac
hose OD) over the hose, washer and ball. Now
shrink it and you're all caught up. You could
probably get by without the washer but I didn't
want the ball to pull in.

I run a 98 TB in my car and had to take up a good 3/4" of slack. What I did was took some brake line, used a dremel to cut a slit down one side, and then cut it to length. So it basicly slides right over the excess line between the end of the line and the pedal. I used heat shrink for wiring harness' to hold it in place, double shrinked it and it works awesome.

how much difference will doing this make. Will it change throttle response and over all power?

For TCS cars follow the throttle cable back from the tb till you reach a little "black box" on the cable. This "black box" is two pieces, unclip it. Throttle cable housing itself is two pieces also. After unclipping black box, spread cable housing apart to remove remove slack, pull together to create slack. Snap black box back together. Don't know about non-tcs cars, believe they are different. Takes about 8 seconds.

Bumpstop makes it so the blade -can- open fully.
Slack may need to be taken out, to make it so it
-will- with the pedal. Even if you get the adjustable
runs snug you may or may not have enough draw
length minus slack in the pedal run (on a TCS car)
to do it. This is where the spacer comes in.

Soo you would only do this "if" you have a slack after TB bump mod. In my case, I don't have a slack at all.
