legit dry shot questions ive decided to go with a 100shot on my m6 99' TA. ive read all the crap argued each way with dry shot vs wet shot. still i have some questions that were not answered. i have read several stories saying contradicting things.
1.Will the stock injectors and fuel pump keep up with the demand
2. does the pcm go to lean before it compensates and adds fuel? and how quickly will it adjust?
3.about what a/f ratio will the pcm run with the 100 shot?

1. It depends what you have done. On a mostly stock car the stock fuel system should be able to support a 100 shot without a problem. The only way to know for sure is to scan the car and monitor the injector duty cycle.
2. I can't speak for others but I have never experience a lean spike. As soon as the nitrous would cross the MAF it would start to add fuel.
3. The A/F ratio all depends on the location of the nozzle. Generally, the closer the nozzle is to the MAF the richer the A/F. You'll want to monitor the A/F with a wideband to make sure you have a proper A/F ratio.
