would a mbc in parallel control spikes up high as well as down low? - shl rider 2004-03-19 11:41:31 (887 views)

Whenever the boost reaches the set value of the MBC, the MBC bleeds off the extra - Mark P 2004-03-19 11:52:48 (884 views)

Everywhere ... When used in parallel, it would control the upper boost threshold - jbear@work 2004-03-19 11:45:05 (776 views)

That is correct. That is how mine is set. - DAP 2004-03-19 11:46:27 (620 views)

If you don't have boost spikes and you aren't doing any fuel upgrades, the chip by itself is fine. - DAP 2004-03-19 11:08:02 (599 views)

Totally depends on your setup and what you want to accomplish. - W0LSC0D(Anti-Rice) 2004-03-19 09:44:49 (783 views)

Is it correc to say that MBC alone will yield the most power because... - Swank4 2004-03-19 10:18:16 (786 views)

Peak power may not be much higher, but it will yeild more area under the curve... - Verrückt 2004-03-19 11:16:19 (667 views)

Yeah, that is why I say it depends on your objective. I want power AND reliability. Therefore.... - W0LSC0D(Anti-Rice) 2004-03-19 10:32:49 (705 views)

Unless you've got fueling upgrades, you probably want the MBC in parallel with the N75. - DAP 2004-03-19 10:39:57 (707 views)

Re: Unless you've got fueling upgrades, you probably want the MBC in parallel with the N75. - iturk 2004-08-15 08:18:59 (651 views)

"What's better for the engine" They are all fine. - W0LSC0D(Anti-Rice) 2004-03-19 10:35:20 (625 views)

Are boost spikes EVAR good for the engine? - reefer_bob 2004-03-19 10:32:43 (613 views)

Very nice simple explanation! Why didn't I think of that!? - W0LSC0D(Anti-Rice) 2004-03-19 09:24:32 (520 views)

so should we run MBC's? - 2000s4biturbo 2004-03-19 09:14:15 (603 views)

Absolutely no need if you happy with your current boost delivery. - W0LSC0D(Anti-Rice) 2004-03-19 09:47:12 (678 views)

In parallel with the N75, sure wouldn't hurt it seems.... - reefer_bob 2004-03-19 09:18:50 (790 views)
