anyway.....problem seems to be fixed, still having a slight +/- 1psi fluctuation, but its a lot better than it was

 

what brand of MBC is it?

some mbc's are very hard to, set to the right psi that you want.

 

bring me asian girls....lots of them

 

Stepper motors, wiring, electronics, a sensor, and more vaccuum lines definitely sounds much less complicated than a ball, spring & screw...

 

LOL... the profec B has been proven over and over in tests (aka sport compact car & turbo magazine) , respected by dyno tuners (ask John at SS and Enthalpy), and proven on many people's cars (I know many people on TR have the profec B and B stage II).

It dosent spike like a ball and spring does, the "locking screw" dosent get loose and all of a sudden your running higher boost, you dont have to open the hood to adjust it, its not THAT expensive (used profec B's can be had under $200), and its easy to tune quickly for changing conditions (gas, weather, or others).

Putting a manual boost controller on a 1998 supra TT.. Is like leaving your 2 year old daughter with a bad day care...

 

funny thing, is that alot of the extremely high horsepower supra guys on SF, are running hallman mbc's, rich hit it dead on the nuts...i had a profec B, and liked it, however, if i were to be running a very high horsepower car, i'd try and keep it as simple as possible...different strokes for different folks

 

it's the turbo xs one step

 

you met my friend lauren right ???

 

i've actually seen a decent degree of success with those, for every rotation you make with the screw, it adds or subtracts 1 psi of boost, and seems to be pretty accurate

 

yes, she was beautiful, i didn't know if you too were an item or what not so i just went the other way and smoked a couple bowls, lol
