hi, well i just finished installing my DC sports downpipe/cat delete combo. everything went well, fitment is good, no rattles. question is will installing a downpipe lower your boost levels? this is running an MBC. i know when i put a downpipe on before running the stock BCS, it increased the boost. that's why with an MBC, i'm asking if it's normal to lower the boost, i figured it would increase like with the BCS. there was no cat in any of the situations posted above, just the addition of the downpipe. thanks.

 

normal!!! no back pressure free flowing,,,,

 

how come it goes up if using the stock BCS though? anyone?

 

c'mon, anyone else have an opinion?

 

bump

 

Whats a bcs?

 

boost control solenoid. basically running the stock ECU controlled boost control.

 

If you have a MBC, why don't you set the level of boost that you want.

 

how much psi did you lose? what downpipe/cat did you have before? your boost should increase not decrease when you put a downpipe/cat delete on if you are running the stock bcs or a mbc

 

you do not need to lower the boost using the mbc... did you have the mbc on the stock dp too... or did u install it after teh dp install... just set it at what u want and that's it...

 

the only change(like i said in the first post)was the downpipe, already had cat-delete. i lost about 2psi. i remember when i had a downpipe before with the stock boost control, the boost went up, that's whay i'm asking if it should do the same with an mbc. i know how to use a boost controller and turn it up to where it was, i'm not a newb. the question was should the boost have dropped with it set at the same place as before the downpipe install? then again, now that i think about it, maybe since yesterday was the 1st day into the 80's up here, that could've caused my loss in boost.

 

Just tune the sucker back up to 22 psi and call it a day bro...done deal.

 

i understand that i can do that, i'm just wondering if this is normal or not.

 

Hondafan-I notice that when the temperature outside drops(significantly), my boost actually goes up, beyond what I would like.

 

yeah, that's why i was saying maybe it's just related to the weather warming up significantly here the last couple days and not the downpipe at all.
