weird problem, 1st gear, no second turbo, all others gears, 10 psi
Like the topic says, i have a weird boost problem. On my first gear, my first turbo kicks in, and after... nothing, no boost, then i shift to 2nd gear and full 10-8-10 boost pattern....
anyone could have an idea of where is the problem coming from?
any advices would be appreciated.
Thanks
Max

i had a similar problem once. check the 2 vac hoses under the crossover pipe as well as the above solenoid. also check the 2 rubber hoses that go from the turbos to the bov/crv.
i never did find the exact solenoid that would fix this, but did resolve the issue by replacing those 2 vac lines, new turbo control solenoid, 2 new rubber hoses and a Profec boost controller.

sounds like one of your check valves to the vacuum chamber either broke or popped off. Start in second gear and go WOT at speed, see if you get 2ndary boost...if no boost, shift to third and I bet you get 2ndary boost in the next gear due to the vacuum you create instead of stored in the chamber.
