I know that using programers with nitrous is dangerous cause they add timing when with nitrous the oppisite is needed. But till i get a dyno tune it the only way i have to raise my limiter an shift points. Setting the programer at 87 octane shouldnt be to much of a bump in timing to cause detantion with a 75hp dry shot.

i don't think handhelds usually add enough timing to worry about knock do they?

I wouldnt run a handheld tuner with nitrous ever... especially on a dry shot. I'd put it to a stock tune, maybe except for shift points and speed limiter, run some 93oct gas and put a wet shot on it if you want to spray without being tuned... make sure you go to some colder spark plugs (NGK TR6) as well... you should be alright. I wouldnt go bigger than that 75 shot though.
