at 3.63 psi. when i push gas pedal half and hold it for more the n 20 seconds
check angine light comes on and the car does not run like it should.
when i pull over to check the car and put the car on neutral rpm goes up to 1500
rpms i though it was the map sensor and i unpleged and nothing
happened. so it is the map sensor.\
but what should i do i do have missing link valve.
please help

 

well what are you throwing a cel for

 

I wouldn't rule out the fact that you're using a **** hack-tune with that missing link crap.

The MAP sensor can only take so much pressure, don't forget, unless you have forced induction the pressure is negative. You may simply need an aftermarket MAP sensor.

 

Syndacate has your answer i think. Stock maps are only rated for 10 psi, but that varies with different turbos because of cfm. Get a gm (general motors) 3 bar map for around 50 off ebay and you'll be fine.
