Thanks,
Scott

Recently read an article that said the stock injectors were running at 108% duty cycle. "dont quote me on the number" but it was over 100%.

The problem with NO2 is usually people run lean and burn a piston. So if the car is already at full duty cycle, it could cause issues.

However, only shooting 35-50Hp will have a nice positive effect, it would cool incoming boosted air actually giving you a double effect. Your charged air will be cooler and denser and you are also hitting it with NO2 the power adder. I would say a 35 Shot would yield you close to 50 Hp.

Or you could run a wet kit?
