How do we do it with our motor and tunes?
If you handed me $$$ for one and said I had to install it this weekend, I would
- Nitrous Express 20421-10 or -15 (manual switch, save $) or 20422-10/-15 (wet systems in the Proton line)
- Revert to stock tune
- Start with the "35" N2O/Fuel jet pair (next is 50)
- Dump in some MS109 and try it.
