Did you recalibrate your speedometer after you installed the 3.73? Also check your ram air for leaks.

50 mph with an auto. Roll Racing is pointless and roll racing with an auto is even more pointless. The autos in these cars are way to unreliable with when they want to downshift and what gear they want to downshift into. The shift-kit will help and all but if you really need to roll race with an auto, try from a lower speed.

None of those parts should cause these issues. If it's running that lean, I would think that detonation would present also.

eminem1833, are you throwing a check engine light?

Guys, will the TPS cause this sort of issue?

Maybe he got oil on the MAF sensor?

Do our cars have some type of limp mode? I know alot of newer cars do and it kinda sounds like that he's experiencing but I'm new to mustangs so i don't know if they indeed have a limp mode or not.
