| | speedometer doesn't keep up with car
So I've been having an issue for the last few months where under rapid acceleration or uphill accel (more load) the speedometer wont keep up with the car.
If i do a WOT run, I'll stop near end of 3rd or mid 4th and the speedo will be showing around 35mph or so pending when i actually rolled into it, and then when I press the brakes it will rocket up to a more accurate speed.
Under moderate accel it will lag a bit until I let off the gas a bit and then it will catch up.
I put in a new VSS sensor and that didn't really help anything at all.
Started when I put in a new Built T56. Any ideas?
