Well i installed the gm 3bar on my 95 integra ls-t and now the car surges the rpms up and down... but wen i disconnect the vacuum hose the car idles fine... is there a certain place that i have to connect the vaccum line?

 

is it chipped/ programmed to run a 3 bar ?

 

seems like you installed it without a tune
you have to be tuned for it

 

OKK thank you i did sum more research and no its not tuned for a 3bar ..its on a street tune right now runing 8psi but i plan on tuning it at 10psi by j-k tuning after i upgrade my clutch

 

Yea you def have to program your ecu for a 3 bar. The voltage is different of course.

 

Like everyone said you need a new map to use a 3bar.
