Well I put in the jets for a 75 shot a few days ago. I already had 1 step colder plugs and 190lph FP installed, it spray fine but tonight on the way home I hopped on the spray in 3rd. As I got closer to redline, about 6k all of the sudden my CEL started to blank so I let off right away. I babied the car all the way home but nothing seems be wrong, no loud ping or knock, no lack in power. When I got home, I check the code and it pulled up 0505? 0505 as far as I know is a ghost code but the flash cel means a misfire so what the heck? any ideas?

 

could be to rich causing high RPM blow out whats your plug gap

 

Gapped @ .35
Also whenever I close my bottle, after a period of time I check on the gauge (like overnight) my nitrous gauge reads zero. Is this normal or do I have a leak somewhere?

 

Yeah, I'd say you have a leak. Make sure you have teflon PASTE no tape on all the connections.

 

well I called NX regarding the potiential leak and they say its normal. Supposely they say the way the teflon line was built, if nitrous was left in the line over a period of time with the bottle closed. The line will loose pressure...
Also the 0505 or any cel hasn't come on since the first time I posted so far so good.

 

um.. isn't 0505 the all-clear code?

 

0505 is a clear code. Means everything is all right, happens to many others with Max's so I wouldnt be too concerned. If you are having no symptoms, reset the ecu and see if you re-encounter the code.
