The issue I see with re-tuning the PC is this. To the best of my knowledge, I could be wrong, you cannot run two maps simultameously. I realize it has been a while since I have played with the PC software. However, I havent heard of a PC that has two MAPS. Moreover, that can be switched on the fly by a signal or trigger. If it were me...I wouldnt use an off the shelf kit per-say. I would use a traditional fogger nozzle (Fuel & NOS). Buy a new throttle body, have it drilled & tapped or a bung welded on to accept the nozzle. T-Tap the fuel line, install a small fuel pump, and whatever size bottles you wish. Next, a full throttle switch or a button (I.E. Horn) and an arming switch (ACC on Dash for us SEEG Guys). Lastly, you will most certainly need it tuned. Start real fat on fuel and light on the NOS. Watch out for detonation and keep a real close eye on EGTs. Remember...Lean is Mean-Rich is Safe. As a safe precaution, I may pull a little timing out of the MAP while getting my baseline #s, then handle the jetting. Bring the timing back in when jetting is getting close. Detonation=BAD.
Im curious to see the HP#s. I had NOS on my Sea-Doo, Ski-Doo (What a pain keeping the bottle warm), GSXR, you name it. It haddnt even entered my mind for my SEEG.
Hmmm...
