Do I need to tune my car for nitrous?

 

Generally speaking if you have 93 octane fuel you don't need to pull any timing for anything under a 150 shot, I think you need to pull roughly 2 degrees for every 50 hp so 6 degrees for a 150 shot! You should be safe without a tune up to a 125 shot or at least thats the consensus here! Don't forget to get colder plugs or you can say goodbye to your engine!

 

Dry kit you have to and wet kit you can get away without it. I'd get at least a wide band reading on the juice to see if youre ok with your A/F ratio. Mine is tuned for the nitrous all the time, safest option IMO.

 

Yes...

 

I would still tune it for nitrous, get a wideband in your car to. With a 150 shot thats to risky. I have heard of people doing a 100 shot without a problem. But I would not risk it better safe then sorry.GET A TUNE.

 

Yes...

 

Honestly, it all depends. If you are still on the stock tune, you could probably get away with it. I think the stock tune has around 24 max timing. However, if your car has already been tuned, you will need to pull timing before you even think about spraying it. Alot of times you will see 30 degrees in an agressive motor tune. IMO, this is too much to spray on

 

we added timming to my cousins car with 100 shot, we run 26* total and its been together for 3 years now. bone stock ls1. thats with a wet kit.

my vett i run a 125 shot, stock tune with dry
put it on the dyno or get a af gauge and see what your looking like

 

If the computer hasn't been touched as far as tuning goes then you should be able to get away with a 100hp shot with no problems. For the 150hp shot i would suggest getting a tune to get he full potential out of the car and to know your safe to spray.

 

I agree you should be able to get by with it, but if it was me I'd hook the computer up to it just for good measure.

 

I'd get it tuned to be safe
