What stall for nx???
This allows him to do two things. First retard the timing only while engaging the nitrous and second it has a built in rpm window activation. He has his come on at 3800 rpms and shut off at 6100 rpm's. This way during launch and while shifting gears the Trans is not getting as much abuse.
He improved 1.3 seconds from a 100 hp shot.
Good luck,
Al
