Wont go up to 7K Rpm

[240slidekat]

ok ive read and heard that the redline on the rb25det's is 7000 rpm ive even heard of people goin to 7250rpm. i have a series 1 rb25det and it wont go up to 7000rpm. it goes all the way up to 6800 and thats when it cuts. im using the safc2 for the tach and i also have a wideband with datalog hooked up and it shows that it cuts at 6800.

any clue of what the hell is wrong with my motor? anything i can check? thanks

no expert but could it be the nuetral position switch wired wrong, keep you from reving high?

i just thought i'd post because i also remember reading that it should go past 7k and back when i dynoed mine cut out at 6800 also. i'd love to know if anyone has anything to say on this subject. do i need to go back and play with some more wiring or what?
