NOS

It will probably loosen the Converter a bit if you stay in a 100-150 hit. Controllers are for all user's of NOS and should be considered for your car. I like a way to check Fuel Pressure on the big end and a AFR will definitely ease the tune. Race Gas most likely since you have some compression and with a timing control you may can run a mixture. I personally think your combo will really like a nice hit if you are racing 1/8th mile and with your gear I don't see the tongue hanging out at the stripe. Just make sure you have your Fuel System in check.

It's a power adder just like anything else IMO and if you get a decent tune your ET will substantially decrease....

Good luck,
