Not sure what to do

k so me and my two friends left a party at like 12 or so at night and are driving in butt fuck no where when we start being followed by a truck so we turn on a dirt road that was a 25 mph when it turns out its a cop behind us and he turns on his lights. so we pull over and start freakin a little cause we had a few beers. the cop comes up and tells us he pulled us over because a fifty foot strech of road was 15 mph speed limit and we were going 25... but it was not posted we just should have known that. So we all figured he wanted to see if their was alcohol. he gets our id then comes back with a breathilizer and tells us all we have to blow or tell him we had been drinking. we all said we hadnt so my friend who was driving blows and passes then my friend in the passenger seat was asked to step out of the car where the officer pretty much tricked him into telling him he had a drink tells him to sit back in the car and calls me to blow so he makes me step out and makes me blow four times and he wont show me the results on the last one he looked at it and asked me why i was lying to him so i thought it registered something so i said sorry sir i was nervous and i had a sip of beer tonite.. i go back and sit in the car and the officer comes back with my citation and on it it said mip admitted to drinking a beer but no number and same with my friends so i asked the officer if i could get what i blew written on my citation but the officer didnt say anything and just left.. so i asked again out the window but he wouldnt tell us saying it doesnt matter.. my friend in the front seat got mad because he was tricked into admitting he had drank but we didnt get the results of the tests the officer then addmitts we all passed but the two of us that admitted get the citation then he leaves now we are wondering if we could fight it because we techincally passed i just wont to hear thoughts because im pretty angery at how the officer treated us and there definatly was an intimidation factor in their. should i fight this thing or let it slide because the penalty here for mip is way harsher than anywhere else i have seen i would get 25-40 hours of community service 250 dolar fine 2 months w/o my license and 6 months supervised probation. what should i do?
