My problem is that some times my primary turbo works and somtimes it doesnt. If and when it does, it hits 12 psi tell transition at 4500 rpm and then leaks down to 5 psi. What is going on. When I disconnect the negative battery terminal to reset the ecu. 75% of the time it works and when it does work it last only for 5 minutes or so then shuts off. If I full boost it in any gear it wont come on in the next but if I part boost it to 6-10 psi it will come online in next gear. Could my ecu be bad and how much will it cost to reprogam it.

 

Your ecu is probably fine. The control system for the turbos is where your problem lies. Search this forum for troubleshooting turbo problems, and plan on doing the hose job, or paying someone a wad of cash.

 

Dear god thats a problem if I ever heard one. Is there a rotary specialist in your town. It sounds like mulitple problems.
