Need help with system for Corvette LS2 based system I have read the FAQs and done some research using the search function. I appreciate very much the information on this site.
I need help specifying and procuring a nitrous system for use on the following 2005 C6 Corvette Coupe. The car has been upgraded by MTI Houston with their Devilray 427 ci package – a sleeved LS2 based engine. Car has relatively high compression 12:1 and a mild cam 116LSA with 228/232 duration at 0.050 and 0.588/0.574 lift. It runs great on just 93 pump gas - no alcohol, no boosters. MTI reworked LS2 head flows 336 cfm intake 240 cfm exhaust at 0.650 lift.
Some engine specifications can be found here:

The motor currently puts out 507 rwhp and 519 rwtq NA at SAE conditions. Dyno chart by MTI here:
I am looking for a nitrous system with the following features for street use with some occasional track use:
Clean professional installation and ability to install without permanent modification to engine or intake system. Be able to return to stock.
Multiple safety features to include fuel pressure shutdown, RPM window switch, and wideband AFR shutdown. I have a lot of $$ in the motor and don’t want to risk damage.
Indication gauges for AFR, N2O bottle pressure positioned where the driver can monitor (pillar gauges or other)
Indicator lights for N2O system status armed, offline, etc.
Purge system and bottle blowdown kit
Remote bottle opener that engages when the system is armed
Automatic N2O bottle warmer
Low profile arming switches (open to location)
100-150 rwhp performance (probably won’t be looking for any more down the road)
Low well defined maintenance requirements
Stable bottle mounting such that the roof for the coupe will still be able to be stored in the back.
Things I am open to considering:
I am not sure if I need a 2 stage or 1 stage system at this point. I am concerned about being able to use the system due to lack of traction if it all comes at once.
Open to either wet or dry system. I have a good NA tune on the engine (done by MTI) right now. I would rather not have to change my NA tune for normal driving around. If any tuning is needed when the system is on N2O, I will have to find a local tuner to manage.
Anything that improves the safety on the system.
Not sure if I need any fuel or injector modifications.
I either need to be able to install this system myself or if anyone has a contact for a good shop in the N. Kentucky or Cincinnati OH area – or within 200-300 miles.

Welcome to the board!
I would recommend a Plate system (its a wet system) as it is easily removable and does not drill into any air ducts or intake or anything like that. Nitro Dave of Nitrous Outlet carries the NOS and his own Nitrous Outlet Plates (I am running his LS1 Plate), Nitrous Direct has a LS2 plate system also. Both are board sponsors.
The only odd thing in your list is the opener automatically opening and closing with the arming of the system. Perhaps NX Ricky can come up with a way to do that (shoot him a PM).

The remote bottle opener (mechanical type) can't run off the same switch since it is only a momentary type operation. You would have to put a micro switch on the bottle opener and have a way to adjust it or put a pressure switch on the bottle so that when it reaches that pressure, the opener would shut off... then there's the issue of closing it. It can be done but it gets a little involved. It's also not the safest thing to do.
The solenoid type opener can be done more easily using a relay, but should be run on a separate switch anyway. Either way, if the N2o solenoid sticks open, you should have a way of completely shutting down the system.

The NOS opener will work off the arming switch. It uses a control box with fused constant and switched power. The switched power controls the opener, apply power to open and remove power to close. Or we have the Pressure On Demand (P.O.D.) system that will control the opener and a heater. It has a small handheld programer that will display bottle temp, pressure, and show if the bottle is open/closed and if the heater is on/off.
