I know this has been covered before, and read though some of the searchs, but started falling asleep reading.....so I have my first boost leak and get about .45 to .48 bar boost and that's it. This is after a night on the town, cruising boosting yes, was fine before and had a small spike then held .7 to .75 the slowly came down a little. The car didn't have any problems that night, next day I get in and well I only get the new lower boost level. Car doesn't smoke still runs fine. Car is a 93 with 66k on it, with a reman mazda motor, about 3-4k ago installed from previous owner. It has the following done, apex-i intake, hks downpipe, stock midpipe, hks carbon-ti exhaust and greddy type s boost controller. Im not sure where the leak came from but decided to get the hose kit so I can take the uim off and replace the hoses, so my question is there anything else that I should look at while Im in under there?


Sorry for the long story but just wanted to get you guys all the info.

thanks in advance for any help.

 

nothing else but hoses to check while the uim is off ?

 

Are you sequential or non-sequential?

 

sequential, boost is the same on first and second turbo, they still both work, just low boost.

 

Just start with the normal troubleshooting:
