my bro bought a 75/150 wet shot zex kit with dual purge. and i took it to be installed today, bro is at work and doesnt have time, and i asked if it should be dyno tuned. the guy told me no, i found this kind of strange. he told my brother it comes with something that retards the timing when nitrous is in use? is this true what so ever? also we had them go about and install the 75 jets, im assuming it will be easy to install the 150's once he's ready to step up? also about how many passes will a 10lb bottle last?

i cant wait to get a picture, hes going to have the purge come out of the ponys mouth on the grill, my idea of course.

without messing the cam gears or playing with the ECU I don't see how you can retard the timing.

^^ i think it goes through th ecu. not sure man.

as for the purge yeah it sounds cool looks cool but really it not that functional because you can't see it..... the cowl is the best place for it.

i dont know much about purge. i was under the impression its just to get air and condensation out of the tubing, correct? i guess you need to see it to make sure everything is out?
