Fuel cut @6500 rpm

[SPEEDRACER88]

My fuel cuts at 6500 rpm (according to the factory tach) what gives, can the factory tach be that far off?

yup,
your prolly accelerating too fast for the needle to keep up and indicate the proper rpm. of course im talking mili seconds here but still ive seen it on other high power vehicles
(btw im not kidding)

Stock fuel cutoff is 6500.

Stock fuel cutoff is 6500.

The reason I asked is that on page 8 of my handy dandy SVT owners guide/supplement it says "Redline- 6500 rpm (fuel shut off at 7000 rpm)" :shrug:

Well its wrong, thats for the older cobras. My tech card and book that I got with the car says 6500 fuel shutoff.

Also when I got my Predator and tune from Rick (Amazon) he set my cutoff to 6800.

Thanks, thats what I wanted to know (if 6500 rpm was the stock fuel cut) I'll shift a little sooner then.

Most guys get the best performance shifting early...like 6200rpms (for stock) or lower (as boost level increases). I have my shift light set at 5900rpms because of the higher boost I'm running.
