Okay so tonight I went to test in tune at the local track. I have a 03 mach 1 auto with the NX kit wot switch, NX window switch. Window switch is set for 3200-6000 rpms so when I take off in 1st gear it sprays but once it shifts into 2nd gear it doesn't spray. And same from 2nd to 3rd it won't spray but if I floor it in 2nd nitrous kicks in but going into 3rd no nitrous. And I leave the car in drive. No Manuel shifting. The car is tuned. Think it has something to do with the tune? Cause the car won't shift till like 6300 rpms so the nitrous shuts off at 6000 rpms but it should kick back on once it goes into 2nd but it doesn't. If anyone has experience this please let me know what you did to fix it. Or it might be the tune?
