first......problem is i used to have a greddy profec b boost controller but it went out on me and now im trying to find a way to hook up the wastegate hose with out the boost controller. my tuner said there is a way to do it but im not sure and need help. well right now i have a hose going from my wastegate to the pipe where it connects to the turbo. am i doing this right? dont have any vucuum hose going to the wastegate at all.

second.....don't know where to connect the plugs for my gm 3 bar map sensor. the plug for the map sensor looks like the plug coming from the iacv. should i disconnect the iacv plug and plug the map sensor to the side port of the throttle? im lost and need help!

 

alright so what ur saying is ur gonna run off the spring? in that case leave the hose going to the turbo to the wastegate and that should put u at whatever psi ur spring is rated for..
and for the gm 3 bar u need to disconnect ur stock map sensor plug and cut and splice the wires into the plug that you should have got with your map sensor it should be orange..
google how the wires should be put into the new map sensor plug.
