After reading that, you need to adjust your tune. The tune for a 100 shot is not good.

 

yeah +1

a nitrous tune from a dyno is irreplaceable as compared to a handheld tune. also, if you can find 91 or 93 octane gas close to home, it's worth it.

 

Just take your "tune" off. There is no reason for any form of tune for a 100 shot or less!! Period. End of story.

 

Im being vague because i have no idea what this is...its like the car is back firing...the nitrous works and i can feel the small push but the car will randomly backfire or pop and my tune came from American Muscle. We have a place here in Amarillo that can tune my chip..Maybe i should just look into that.

 

So your saying that I should just run the car with the stock computer tune??

 

The tune itself is not good or the fact that im trying to use a 100 shot tune with a 75 shot is not good??

 

Yes. Final Answer.

 

Plus, are you running one step colder plugs?

 

With only a 75 shot you don't need to adjust your timing at all. I'm guessing in your 100 shot tune they have pulled 2-4* of timing (if possible with those kind of tunes).

Like I said, this is what you need to do: Run 91 or 93 octane, preferrably 93 octane, make sure the tune you have hasn't changed the factory global spark, make sure you are running stock heat range plugs and make sure no timing has been adjusted. Running your car on the factory tune would be better than what you are running now. If you want AM.com to write you another tune, make sure they don't adjust the spark and timing.

If I was you I would not run your nitrous until you get this worked out. With only a 75 shot I really don't see the need to take it in to get it tuned. If you do take it to a shop to get tuned run a bigger shot.

 

I ran 100 on a stock tune w 93 in it for a long time.....sounds like ur rich as ****
