tuning dry nitrous with hp tuners
hey i am new to tuning with hp tuners, i installed 42lb injectors on my car and was wondering how you guys are tuning for a dry nitrous kit, what i want to do is run my nos 5177 kit with no jets and i was wondering how you were going about tuning with hp tuners. once someone explains what steps i should take i would like to goto a 200 dry shot. by the way i have a forged 347 with eagle h-beam rods and diamond nitrous pistons, stage 2 ls1 heads, thunder 224/224-112 cam, shaner s2 throttle body, and hooker long tubes. the car has a tune from tea for the n/a passes but the tuner told me not to spray on this tune. any ideas where i should start?

timing (high octane table) needs to be reduced alot probably. other than that get the a/f ratio good via the pe table and you should be allright. the only problem is you will lose some power while off of the spray. colder plugs too.
i don't know how much timing to take out and what a/f ratio is safe, try a search for that information or call some professionals for info.

the beautiful thing about a dry shot is you can split your timing tables, so when you spray you can have it drop a ton of timing if you like, monitor your G/cyl and see where your car runs NA and anything over there in the tables reduce the timing 2 degrees for every 50 hp you add. you cant do much about the initial hit lean spike they have, unless you want to make your car run really rich NA.

couldnt you also just pull a bunch of timing via the iat vs. timing table? With a dry kit they tend to hit the iat before reaching the motor and you could have it pull timing depending on that temp.
