Ok i am having trouble increasing boost. A few days back some vaccum was off and my car running Non-Seq without any mod... i drove it for a few days boost use to come at around 4500 rpms but from there on it was a wild ride... i was hitting smooth .9 all the time... Now i have a fully functional sequential setup and when the secondary turbo kicks in boost drops to .7 ony.... I tried increasing it from the boost controller. its a greddy E-01..and on the power fc nothing works... the primary turbo its .9 but when the seconadary kicks in it drops to .7

Can it be that i have hooked up the boost controller wrong.... There were no instructions for installation on the rx-7 with the boost controller.. Which actuator do i need to connect the solonoid to..and which one do i have to cap off... Any pictures would help...

Thanks

Do you think all your Vacume lines are hooked up and correct?

I have had the mechanic check and recheck the vaccums. he found them hooked up correct.. I think so too cuz without the boost contoller the boost pattern is ok... Can it be that i have the boost control solonoid connected to the wrong actuator??

Cuz the primary turbo hits around 12 psi of boost...but the secondary drops to 9.5

That could be it. Its gotta be something with the boost controller hook-up if everything runs fine on the regular stock set up. I have had some questions about hooking my Boost controller. I still haven't hooked it up because I don't know where the 3 vac lines go to.
