I installed the Bushur's MBC controller from underneath the car. Just removed the plate. It took me about 1hr 45 minutes or so.. (probably real slow, but I took my time and zip tied everything down).. The hardest part was getting the hose off the wastegate, but was really no big deal. I tapped between the BOV and intake...

I would recommend going from underneath instead of removing radiator hoses and the fan ext from above... You can reach the mas pipe hose, turbo and wastegate real easy if you put the car up on ramps...

Before the install:

Even with the Dynoflash, I was only getting 15-16psi in first and second gears. In third it would spike at 19 and taper to 16-17 by redline... 4th would spile at 19 and hold to 17-18psi...

After the install:

The boost still tapers, but it is much slower... The boost is real steady and you can really feel the difference... Right now when I mash the throttle, it spikes at 21- goes to 20 and holds it for a long time and finally tapers to 18.5- at 7000 rpms...

Is this two much boost? Should I set it to 20 and have it taper from there, or am I ok?

 

you should be ok. 20-21 psi is what alot of people run.

 

Buschur only set mine to 19 PSI, although I think I am actually getting 20 (according to my gauge). I know several people in California running on 91 octane and running 21 psi with no problems. I myself can get 93 and sometimes 94. So if you can get good gas then you will have no problems.

 

Sounds good to me, I run 21psi on 94 octane, and love it!

 

Yeah I get 93 octane... I also bought a 5 gallon tank of toluene from Sherwin Williams for insurance....

 

93 octane alone your fine...i usually fill w/ 94 from sunoco
