Ok thanks for your time and information

I m confused so i will try to find a Jam unit because I want to look stock user bonnet....i believe it is stronger and flows much better than stock with stock boost level.... Thanks for all the useful info

So no one suggest Jam manifold because they crack easily like stock

Can you send me some pics please.I want to inspect the cracks because I want to buy one and I want to know if they are repairable. Thanks a lot

So it's waste of time and money....what boost pressure do you run?maybe they hold easily the stock boost! Thanks for reply Bean

Do you have experience in one of them?

Only at the collector or they crack outside?does the cracked collector affect?

Thanks for reply Matty gt....so they are better than stock ones because they don't have restrictions.Pobably you get better performance with one of them. That's why I'm trying to find a jam manifold

Yes it does....no matter just drop them on

Are jam manifold reliable?Or the they crack like stock ones? And how much is a normal price for o e of them? Thanks

Change all master cylinder seals and bleed them again

This is my first suspicion Does a cracked manifold affects? Thanks for reply

It is nothing to do with restriction....it happens to all gears Thanks

As title....i am a stock ep91 glanza owner When I push the throttle it boost fine(three lights on tacho an a lot of power and torgue) utlil 5000 5500 rpm the boost lows down (two lights on tacho and less power and torgue) Any suggestions Thanks
