For that spendy tool.

Freeing the cat and thus removing the backpressure opens up possibility that more unspent fuel will just get exhausted out. An EGR actually helps MPG if you have some fumes in the exhaust at certain times the egr can recirculate this.

It is not like you lose alot, again it depends on how you would drive it. Since the power band would be adjusted, if you follow that mileage would remain the same pretty much, with emissions like these cars have you would have to remove a few other things to notice any real improvement.

Like cylinder dropping on block learn with solinoid valve control to make sure the compression stroke does not happen on that cylinder. I came up with a design of a slider glide wedge actuator cam follower thingy that can produce 200 pounds of pushing force. The solenoid is a PWM type.

If you really want to get mpg the ECM coupled with all the emissions is your culprit.

Well that is a much better price than etoolcart had it for! I like the looks of it as it doesn't look like it gets in the way of anything, as the Rear Bank just does not have that much room available for the Kent-Moor tool (not that i could even get it on the Sprockets). Do you think it will hold sprockets from moving when breaking those stubborn bolts loose ? Also you mention the EGR Valve..I did Replace that as well when i did all of the other stuff, and i noticed that the one i put on quickly turned old and white looking? Like it had been on there for a Million Miles, and the Stock one that i took off still looked nice and shinny, at least on the exterior of it. Still don't know why it got that old cloudy whiteish look to it, as it too is a Stock AC/Delco EGR Valve. But i did not really wonder too much about it as that was just appearance and did not think that would affect it from doing it's job.

Also, one thing i have wondered about is i replaced Oxygen Sensor during the Beast breakdown..pain in the ass that was and then a week or so later ran 2 cans of GM Top End Cleaner through it...and wondered if all that smoke going past the Sensor could have hurt or damaged/disabled it??? causing computer to get bad input...and make it burn too rich using more gas...I would imagine not but any ideas or thoughts on that......Thanks, Paul

2 cans? Ive been ok with 1 can but you really should run that stuff before you change plugs at the least and O2 sensor would be good. Ive done it without changing anything and it didnt ruin them so its a tough call. Need to get it on a scanner and see how the O2 readings look. If it reads real slow, its bad.
