im loosing a little 2 much power at higher rpms. i found a small split in one of my boost lines. i repaired it. how do i test the system? i plan on the liquid tt soon. then i can at least have some diagnostic ability. in the mean time, whats the best way to check. i know i need a boost guage.

 

You need to make a boost leak tester or pressure tester. Heres a DIY. http://a4mods.com/index.php?page=web...boostleak.html

 

thanks for the link. i dont think a compressor is necessary tho. a hand pump with a guage on it should do.

 

I used a bicycle pump and it was just enough pressure, but a portable compressor helps if you have it.
