My car has been running with non-seq twins for about two months flawlessly. One morning the car just decided it did not want to boost anymore. I remember that it boosted fine on the way home.

Checked under the car and found that the tack weld to hold the flap open broke.
Took it to Neptune in Huntington Beach, they got me help to weld the flap back in place (open position).
Left the lot, still no boost.

Full Non-sequential twins.
No audible boost leaks.

Where should I look? Is it possible that the flap inside the manifold, broke?
Would be willing to pay somebody to come check it out and provide a solution, i'm in Long Beach.

 

The car is making zero boost through all RPM?

 

Yes

 

Last night my car wouldn't start, checked my batter terminal. Re-connect batter terminal. Started fine. Drove off my lot, turbo Spooled! I let off the gas before it could go any higher than 3 psi. Boosted one more time to 3 psi. Came to a stop, then the turbo stopped working again, everything else seemed fine.
still no boost

Note this is a full non-seq. twin setup.

 

Car just decided to start boost again. No odd smell, no audible boost leaks, no oil leaks. I don't even.. i just can't, sigh.

 

lol, bashes a "budget" tuning shop online. Willing to pay someone to fix a non-seq setup.

 

Could be a blown wastegate.
