[Mk3] [Turbo] Manual Boost Controller VS Electronic Boost Controller

sw20GTS

Let's say I am running stock ECU, stock engine, stock fuelling and the only mods are FMIC, straight intake, downpipe, de-cat and SS exhaust.

My target boost will only be around factory levels, not planning going higher than 1.2bar. Would an EBC make a lot of difference from a MBC?

Any thoughts?

Just my 2 cents mate but i very much dought it, i run exhaust,filter,downpipe and st205 on mine at 1.2bar with a gts chris mbc and ive never had any issues with it at all.

In comparison i used too have an avcr which used too constantly overboost when it got quite cold, hence the switch to the mbc, i never noticed any difference between the two!

You'll need a FCD as well if turning the boost up.

Did notice with my gts chris mbc that now its a little damp/cold it did boost to .98 (rev2) from .91 when temps normalish ,so was thinking along the lines of a Gizmo ibc which has had very good reviews and will keep boost down better than the others as it constantly adjusts (so I've been informed).

MBC's are good, cant complain at what you get for the £

I switched from a GTS Chris MBC to an AVCR, and the difference is huge. The best gain is allowing full control of when the boost comes in and how hard, something you cant adjust with an MBC

what's your engine?? rev3?? fuel cut is 17psi(iirc) so you wouldn't need one if you we're running under that, i think the s-bits FCD only goes to 17psi anyway, so it'd be pointless lol, if you want this MBC hooked up and VSV disabled though i can help with that [thumleft]

first rule

NEVER fit mbc with out an accurate boost gauge its the most important thing ive ever fitted to my car.

buy a guage and wind mbc right in so its at lowest setting, then repeat on an air feild prefereable untill correct boost setting is reached

Was a bit worried about 1 bar on my rev2,about to fit bungs on the japspeed so that may bring it down a bit.

The MBC works just fine once its set,just be aware on cold days it may boost a bit more.
