Yes I know, not another one of these threads!

My situation is a bit different. I have searched and not found anything similar to my situation. I have a 94 touring with 50,300 miles which is completely stock aside from a stock downpipe from a Japanese car. My FD is over boosting to 12 psi and hitting fuel cut in 2nd-5th gears and I am stumped as to why. I have faced these issues with my turbo FC but I had an intake, hi-flow cat and a downpipe. Any ideas? Thanks!

 

Check your wastegate line off the actuator.

If you have to, you can buy a reliable boost controller like a Greddy Profec B and see if that solves your problem.

Stock Seq twins can be a huge PITA to troubleshoot boost issues due to 15+ yr old solenoids, check valves, vacuum hoses etc.

 

Yeah, I checked the obvious stuff so far including the waste gate actuator line. I will start to check all of the solenoids etc. Seeing as how most people with a stock car and sequential turbos seem to have the opposite problem, I just wanted to see if anyone could point me in the right direction. Thanks for your help.

 

I have had very little time to work on my car, but I was able to unplug the waste gate and pre control solenoids. I am getting 7 psi in all gears. However, when I hook them back up I hit fuel cut in 2nd-5th. This must mean that my problem is electrical such as a solenoid vs. something mechanical like the actuator line etc. Is this correct?
