Well I guess the first question I have is how will the car run after a tune for nitrous? Any different? I know the timing will be retarded a bit. Will 1 step colder plugs make the car run any differently off the bottle?

 

Timing will be retarded and will run a little richer. I have run my car on the nitrous tune on the road and no huge diiference on the street. No appreciable loss with the HT0s compared to the HT1s.

 

I have a question about nitrous too. Im going to run a 75 shot. I am going to get HTOs but do I need a tune? Is there a mail order tune I could get from bamachips?

 

Yes there is. With the Zex kit, you could run a 50-75 shot without a tune. The fuel enrichment system they use ensures that you will never run too lean or too rich.
