i just read this entire thread, good stuff! any of you guys still around??

one thing i heard and was wondering if it was true was that many newer cars (our 1st gen xB's included) is that when you are engine braking, your computer cuts off the fuel feed completely and it only comes on again when you step on the gas or when your RPM's go below what is required to idle. i live at the top of the hill and utilize engine braking to maintain the speed i want all the way down. in theory, i'd be using no gas at all even though the car is on and i don't need to utilize EOC right?

also, has anyone here looked into things like lightened (but not underdriven) pulleys like perrin as well as lightened flywheels?
