No issues at all. The majority of people gave me the same advice when I first was looking at doing this a couple years ago.

It also gave me a warm and fuzzy knowing my mbc was controlling the boost from the one place it originates

 

Cap off the port on the MAF pipe. No need to cap off the 2 ports on the BCS. Leave the electrical harness hooked up to the BCS.

 

OK installation done WG to Actuator

I will drive around like this and pull some logs and then i will try the other way
from BOV.
Easy to do now that everything is in place.
I will post my findings back here With MAP sensor logs

thanks for all the info

 

installed mine by tapping to BOV line for pressure source. Boosting @20psi rock solid. Mine tapers to 18psi near redline.

 

Thanks for the info

 

The FP outlet pipe doesn't have a nipple on it so I went with the BOV line for now. I don't have any problems with it as far as boost stability, but when I switch back to a stock Evo9 outlet pipe I will go back to using it at the boost source.

 

I have a hallman going to the bov and wastegate and I'm boosting 21 solid with no fluctuations all the way to redline, spools quicker too and pulls harder than the other way I had it coming off the turbo

 

What exactly do you mean by "WG to Actuator"? Please, explain.

 

I hooked up my MBC to the wastegate/turbo housing. Car has fast spoolup, will spike at 23 and hold 21-20 to redline. Every other car I have hooked up a MBC to I did the same install with the same results.

 

Sorry i meant housing and wastegate.....

i am a dumb *** sometimes... WG or Actuator same thing

thanks for picking it up

 

BOV line is not a pressure source once the throttle is closed.

 

so you have tried both methods buddy?
if that is the case i am definenatly gonna go the other route.

installed the forge with the stiff spring and the dumb *** forge wont boost anything lower than 25-26 psi on it's lowest setting, had to remove stiff spring and install the lighter spring.

I boost to 22.75 (peak) and taper down to 18.2 psi t redline.

 

wrong spring same thing for me you need the soft one.

 

yip......
damn man I could here the det


babyed it home till i changed the spring

 

What does that have to do with anything?
