    If you increase your air intake (air volume), (by boost, or my increase RPM) its VERY possible to run lean! (not good on a S/C motor) can melt down a piston, melt a hole in your cylinder head, etc.

    works just like a garden hose... more pressure in the hose, and more water comes out with each sqeeze of the nozzle. (just like an injector)

    you can increase static pressure... or use a rising rate regulator that used boost pressure to increase fuel pressure.. (no boost stock fuel pressure) and as boost increase.. so does your fuel pressure. as you increas the extra volume of air inside the cylinder, you have to get extra gas as well to keep it from going to lean. as boost goes up, the fuel you spray into the cylinder increase! you would be amazed at the amount you burn at max rpms!

    are your PLUGS coming out very clean or possible white? (lean condition?) can be one sign you are not getting enought fuel.

    one way to check... is run at WOT for a few minutes... KILL the ski (stop engine) and pull the plugs. and check the condition of them? this can tell you if you are running lean, just right, or too rich.

    easy way to do it, unless you mount a 02 sensor and read it while you are driving it. good luck!

    You are very far from running lean with the few modifications you have.

    If you ever upgrade to the RXP ECU or aftermarket ECU then you will want the 58 PSI regulator.

    well the ski is a na ski of course and the mod ive done took it almost to the rev limiter it turns 7400 the limiter is around 7700 im not runin a water box and its a larger open intake. last time i checked the plugs ther were gettin a lil on the lean side before mods they were that perfect brown color now there startin to grey out and i dont wanna blow it cause i use a shot of nitrous out the hole so i can keep up with a few friends of mine on rxp's works well but the plugs are readin leaneven without the nitrous so i was thinkin bout tryin this regulator but i dont know if thats too big of a jump in pressure i dont wanna start fowlin plus bein too rich hope yal got some good advice + i know i need an rxp but just dont have the bucks for that right now
