I have a chip, and I also just got a k04, but Im still saving for software, exhaust, intercooler and all that jazz. Since im getting the turbo upgrade in the next few weeks and since i got the Forge Boost Controller for free (basically) im just gonna put it on, i just wont turn it up for now. So back to my question should I pay to have it done, or is it as easy as say my boost gauge?

 

u will be fine with a mbc. i am chipped and running a mbc and thats how i change my boost levels, it works very well. if you know how to install it go for it. do you have a boost gauge so you can see what ur boost is at?

 

Boost gauge was my first mod ever! I was just asking how to install the MBC. Should i pay this shop 30 bucks to do it or just do it myself. Did you do yours Jeff?

 

its pretty easy, i just did mine myself and am pushing about 5 more psi than stock. once you do it once, itll take only 20min to put it back in if you decide to take it out(if its cold)

 

Is there a risk to be lean, when you over boost ?

 

ya u could probably run lean but on the dyno at 20psi i didnt run lean at all. i had good a/f

 

Instead of open a new thereat I'll continue here.. I want to learn how to install a MBC, I think I'll need one for daily drive and which one to get ? Does it make different cheap or expensive ?

 

ok install is easy but be carefull cus ur a/f will get messed up. but if u do it its easy. go from turbo to mbc to wastegate. just bypass the n75 valve

 

Jeff, so it is better dont get it ?

 

I hate when people that don't know anything give opinions. Your friend with a tt steal gained 3 psi because his stock turbos are 9b's they hold NOTHING to redline they are too small. Thats why...not because of the mbc. The mbc works exactly like an electronic boost controller...it adjust the amount of air to the wastegate and decides when it opens...thats it.


theres a chance it wont affect your bosot much becuase the ecu may interfere and adjust other things to compensate for the change in boost pressure.
