When I installed my 1000cc injectors, my boost controller stopped wroking.

The actual install of the injectors had nothing to do with the boost controller.

I dont konw why, but it stopped working. It seems to function properly from inside the car (ex-the lights light up and the selector light clicks and it functions like normal), untill you try and boost. Its like the part of the boost controller that actually talks to the wastegate is not functioning anymore-the car just boosts to the wastegate spring.

Playing with the gain or either boost settings has no effect.

Its a Greddy Profec B spec 1 i think, the non digital one with a power button, a selctor, then 3 ***** for gain, low, and then high boost.

 

Some power lead or vacuum line got unplugged.

 

Check your power lines, i was runing mine near my charge pipes and the pipes striped the wires and they were exposed and it looked like the boost controller worked, but it was not

take out the vacuum line and make sure there isn't not a leak in it

but check THE FULL line trust me, mine was hidden so it took me 2 days to find it, i was about to sell the best boost controller i have ever had because of that.

 

For the cost of a new vacumn line, i'll just go buy one. Good tip
