Wtf is this? I bought my car with the turbo kit already on it. What is this thing thats connected to the tb?

 

Check Valves.

 

BWHAHAHAH!! it looks like a preasure regulator from the map sensor (HMT style of corse). there check valves to trick the map sensor taht it isnt over 10 LB boost

 

I had a hunch, but i wasnt sure. I actually just recently realized i had them. They were tucked into the back of the firewall. So they trick the map sensor into thinking that im running under 10psi of boost?

 

yup so you dont throw a code and go into "safe mode".

 

They trick the map sensor into thinking that you're not running boost at all...when you go past 1 bar(atmospheric pressure you'll get a CEL...soo it let's the map sensor think it's still under 1 bar....well it only bleeds of the pressure heheheheh
