Nitrous kit needs to inject less fuel
Hello. I bought a nitrous kit the other day and it is set up to be installed on a stock engine. My engine in my 85 Corvette is modified and put down 344 rwhp and 343 rwtq through a 4+3 trans. It is 10:1 compression and has the stock size fuel injectors (24 lb for 1985) and the fuel pressure is set at 50 PSI. The kit is tuned out of the box for stock fuel pressure. What do I need to do to give it less fuel to accommodate the increased fuel pressure?
Thank you. This is the kit.

Decrease the fuel jet or increase the nitrous jet to get the proper mix, assuming that it is set for stock pressure. I would probably run it like it is to see where you're at. Better rich on fuel than the other way..
I used that kit for a long time. Had a lot of fun also. It never let me down.
