Dinan on a '06 e90 330

I am sure there are threads about all three of the producrts in question: the throttle body, intake and exhaust. I hate to do a redux, but after searching I didn't find anything about the gains of anyone installing all three mods together.

I called my dealer today and he said I would get about a 20hp increase if I went this route, but that seems optimistic.

I would like to get your opinion on the three mods and if anyone has all three--what performance increase do you see? And of course, is it worth the money?

Thanks

I don't think anyone has done all three together and have dyno'd their car unfortunately. However, Dinan has been known to be conservative when making performance parts so I wouldn't expect a huge power increase. Throttle increase would probably be noticeable though. But it's hard to justify the gains vs. the price of the mods.

one of the members got the throttle body and after dyno he lost few hp.......N52 has a valvetronic system which the throttle body doesnt affect that much, i think it stays open at all times( not sure about that ).... as for the intake, it looks like stock, with dinan logo, might as well get a drop in filter, much cheaper, the only thing i would get from dinan is their exhaust it sounds pretty good, but i never liked dinan so it up to ur prefrence.....

kgfrogman is the one w/ the throttle body install. lost hp on that
the intake -- no proven gains... also, absolutely NO difference in sound... so it's a waste-mod.
the only thing that is proven to yeild some power and have a nice growl is the exhaust.
