i have heard some people talking the other day about how you can put a 50-75 dry shot on an fbody with out a tune and somehow the computer compensate for it. im just wondering if thats true or just a good way to do some damage to a motor.

1. Read the stickies
2. Read some more

Not to trying to be mean but why a 50 or 75 shot?
You can prob run w/o tune but those small shots are almost unnoticeable. When I first installed my kit I shot the 50 pill and a swear I could hear my Ls1 laugh at me. If you want to feel a 50 shot drive your car at night vs the heat of day, feels about the same!!

Check Harris Speed Works for options for sparying dry with out a tune!!!

ohh im not spraying my car its not even close to spray yet maybe one day i was just wondering about the not tunning it for such a small shot, just something i want to know

Graham@NitrousOutlet

It is very hard to hurt anything on a shot that size. That being said, not tuning and dry do not go together.

So if I buy products from another manufacture that claims I do not need tune then who is wrong? Not trying to start any drama but seem to read post where one company claims only way to spray dry is with tuning. One says electronics can solve a issues w/o tune, some say tune is way to go. Reason I am concerned is I spray 100 shot w/o tune with elcetronics to controll fueling and timing.

Graham@NitrousOutlet

The electronics are changing the tune.

Tuning to pull timing make fuel adjustment or using a tuner to pull timing or make fuel adjustments.

I would rather see wet systems in the first place. IMO it is a better setup for relatively stock ls1 platforms.

I heard the computer can pull up to 4 degrees of timing out and adjust and add more fuel but thats just what ive heard when your spraying dry. I myself sent my ECU out and had Frost tune it for 100 shot. Even if i was doing a 75 shot i would've still sent it out to him, it doesnt cost much to tune it and now there is a box you can get were you can run N/A tune and then when you flip the switch for the nitrous on it will go to nitrous tune, so you have the best of both worlds.

Stock tune/motor on a 99 Y body, I was good to a dry 75 shot (logging data), needed to pull some timing beyond that.

Providing you set the nozzle right to be read by the MAF (or use electronics like the HSW microedge), it will add the fuel needed by reading a higher MAF frequency when the Nitrous passes by the wires. That being said, it looks like your a modded 2000. If your running stock injectors, that may be an issue for you on a dry shot above 50.

Nothing wrong with starting small and being cautious. What works for some does not work for all.

You should be fine. I have shot 150 dry shots on 3.8 v6 cars with no tune.

Dumb *** info like this always seems to come out in these threads, and always from an individual with a post count of 50 or less.

Hell, You can spray a 500 shot on anything.... once.

I'm running a dry kit post MAF. I'm pulling timing and adjusting fueling with my HSW Interface and reading plugs after every run.

Research and technical data are much more valuable than these 150 shot type comments^

Very true.

Gotta love it.

Your right you can always do anything at least one.

I always like running a wet shot rather than a dry shot, seems to be an added benefit.

SuperSport01

A dry system is fine if the car has the electronics and/or tune for it. For your average person though, a wet system is best.

I sprayed a 75 dry at first on my vette, felt like a joke now i got a wet 125 shot...runs like a champ!!

Why is it dumb for dannyz to say what he has done to a car before. I guess Im dumb also for spraying a 150 shot dry without a tune? LOL Well Im been spaying this car for 2 YEARS with no tune and no problem. As a matter of fact I have 5 friends that have the same Ls1 motor and nothing under a 125 dry shot. So it can be done.

And if you think im lying why call DYNO TUNE NITROUS and they will tell you the same thing.

There you go then.

IMO I would go with a wet shot. As far as a tune the only thing they tun for is timing. Generally anything about a 100 shot is a good idea to tune. However there are guys who bolt a 150 wet shot on their stock LS1 and run for years

If im so dumb and they are so wrong why hasnt any thing gone wrong in two years? lol

If Dyno Speed says a 125 hp kit is safe i believe them and not you because they havent steered me wrong yet. And yes I did go against what he said about the 150 hp kit. He told me it was a must that i get it tuned but i didnt and its been working just fine.

SargeZ06

Well then I guess you can't argue with Stupid!
