I would You suggest You call marco @ billet design 9549753557 as I run a 100 shot, use it on a daily basis for the last 3 weeks, I run the Piss outta my car. if you install the jets the wrong way than boom boom pow. Marco and Eddie bello have been doing this for a long time they are world class tuners (aem, halteck, HKS, Greddy, etc.) and world class fabrators. see

although they specialize in porsches, lambos, evos, supras and skylines (all lines) they also do great work for BMW's although nothing is "production line" stuff, the custom work they do, is far above the rest.
Pictures of my custom exhaust and nitrous install are coming by august 15th!
