Want More
 

OK here's the deal. I have an 01 Z M6 with tr224 112 QTP LT's w/ TSP td's & now I want to add a dry shot of juice. I do not have nor will I ever have access to a dyno/tune. I have a LM-1 wide band, so I can check my AFR's, which by the way is at 12/9 at WOT right now. The question is what can I run for a dry shot w/o changing the injectors? I don't know jack about nitrous, can I install tr6's & check my AFR's & be safe with a dry shot? TIA for any guidance, I want more power!

I have basic bolt ons, lid, test pipes, cat back, and on a 125 shot spraying threw the maf, i went from 12.5:1 A/F to 11.0:1 A/F when i spray. But every car is different, so just make sure you are using a Wideband the first time you try it.
