1st gear???
 

hey whats up everyone...was just wondering why my 1st gears 2nd turbo doesnt boost...every other gear boosts perfect...i dont know where to start looking...has anyone had this problem before?

umm okay...i guess this will be an unsolved mystery

be more specific. no boost at all? no secondary? etc.

personally, i would look at the check valves first just because it is easier starting there than looking over the entire vacuum system.

HELP ME TOO!!!
 

Ok, let me expand on this. I'm got the exact same problem. Secondary doesn't come on in first, but it's ok through the rest of the gears. I'm hitting maybe 5 psi after transition. Again, all else is cool in other gears. In addition, when coming out of boost, as soon as the gauge hits maybe 2-0 psi, it sounds as if the secondary open up for a split second. It's really weird. Anyway, I've gotten the 2 check valves that could be the issue, but don't have a clue where to begin. One's larger than the other. So...on this diagram, which 2 valves would be the first to replace?

Thanks all in advance...
