Wierd Speedometer problem and fuel cut

[boostineklipz]

Recently when at WOT, I have been experiencing fuel cut. I know should not be experiencing fuel cut at only 18 psi with AFC settings around -27% with 550s.

I noticed that my MPH keeps going up when the car is at WOT. It will reach about 100mph in 2nd gear and when I let off the gas or fuel cut kicks in, it will go back to the normal MPH.

My theory, which could be wrong, was the ECU saw the car was going 100+ mph in 2nd gear and saw that as a problem which triggered fuel cut.

If so, what is wrong with my speedometer?? Speed sensor the problem? Also do you think the fuel cut I keep experiencing is from the speedometer misreading the speed?

The speedo plug's loose on the top of the transmission. The fuel cut is unrelated.

Props to you Defiant. Competely unplugged. Havent test drove the car yet, but maybe for some odd reason that will fix the other problem.
