So today i got bored and figured i would install the boost gauge, so i went to Canadian tire bought some vacuum line 5/32 witch is 4mm , when i was tapping into the T and removed the vacuum line that was on the car i noticed it was worn and falling apart so i replaced the 3 i seen that were ****! , when i took it for a spin it only reads 1st gear 7psi 2nd 7-8psi, did i hook something up wrong or are the other lines done as well here are the pics of the install let me know what you think?? also when i took down the kick plate i found some little pieces of plastic (pics) and i have some black stuff out the exhaust when you rev it up abit (pic)

boost is limited by the ECU in 1st and 2nd... you need to do a hard pull at full throttle in 3rd or 4th and see how the boost looks.

also, if you are replacing vac line it's well worth the extra few pennies to do it with silicone

Typical vac is 18-20 inHg at idle. Mine will hit 24 inHg or so when I am coasting. If you have anything less than 18 inHg when at idle, that is when to start looking for leaks. Makes having a gauge that shows vac and boost a useful diagnostic tool.

Silicone tubing is definitely worth the extra cost. It also looks like you probably need to replace your blend door flap.

It sittings at 20 inHg at idle and 22-23ish inHg when coasting so im guessing there inst a boost leak :) and im ordering silicone lines asap would i get the 4mm with 2.5mm wall http://www.boostcontroller.com/index.php?category=8
