controlling boost spike with mbc

[Dan850r]

Anyone using an mbc inline or parallel to control boost spikes? Im getting spikes and maybe boost creep withe the standard bcs 16t and 3" dp

MBC's aren't great for solving spikes....you may find it will still spike so you will have to lower your boost level, allowing for a spike to what your max acceptable boost. Fitting an ebc would be better otherwise a map.

I'm using a Forge Unos MBC and Never had a boost spike using that, and have been using it for around a Year now, it's not joined inline with the bcs either done away with that just left it plugged in to stop the cel light.

I want to keep the bcs and use an mbc to limit it say18 psi, its got a hlm 304 map on but recently started to spike then drop, ill try a new bcs first

Why do you want to keep the bcs?

[Dan850r]

Id like to keep the stock boost curve if i can, i had an mbc and wasnt keen on the way it boosted, im getting nearly 15psi at 3k now so possibly got a faulty bcs

you cant use both, as said above get a forge unos never had a spike since fitted but did with the map and bcs
