I've seen afm engines in the W body cars make over 550Hp and a few licked the 600Hp mark while still sipping on the high test fuel. all in all, the stick is only for if you want to have fun driving around. but in the end, all things being equal, if I have a bad to the bone car making 600 or more hp, I must have the auto for fear of missing a shift, and also, NOBODY shifts faster than an automatic trans.

Auto ftw.

someone will be doing cam swaps in the L99, im sure of it.

If it works as good as a dual clutch or the latest ZF transmission I'll condsider it. I want to see what the manual launch control is about though.

Auto for me as well.
I just wish the SS was getting the LS3 NO AFM with Auto 6-sp Paddle Shifter like the Vette. On the Vette the Auto is faster than the manual and more accurate! No missed shifts, No bent pushrods! No accidental over revs

my plans are cnc ported heads, camshaft, regular ls2/ls3 lifters and remove the afm/dod as long as one of the tuners has the option to delete the afm,, which should not be a problem since they already make programmers to delete the afm/dod on the dodge hemi engines and the gm truck engines

A friendly reminder to all who want the auto SS L99..
If you plan on adding a significant HP to the engine.. Your tranny WILL fail eventually.. Very likely sooner than later. The T6060 is damn near bullit proof..

the L99 auto really isnt an issue, it is a better trans than the 4l60e and those when built properly can go 10's no problem(mine did in my camaro for years with all the good parts in it), im sure if there is any issues with it once people start modding out the auto's the aftermarket will come up with some bullet proof fixes

also this is not a new auto trans, it has been around since 2006 in the corvette(just with a different bell and tail for the rear mounting in the vette)

While we're on the topic, can the AFM L99 handle a supercharger? What would that end up doing to the AFM? Would it still work? Anyone know?

I'll admit, I'm a total idiot when it comes to this stuff. I know how to put gas in and drive them, but when it comes to fixing them/tuning them/etc, I'm clueless.

That's a good question. Does anyone know what the deactivated cylinders do when they are "off"? If the valves are still opening and closing wouldn't that cause problems with forced induction?

Is SCT the only tuner brand out there? If not, can someone let me know of any other tuner companies? Thanks a bunch.

the only time the afm/dod kicks in is when you are cruising at a steady speed at a very light load ,, in these conditions you would never be seeing boost anyways,,, the only time you get boost is when you are accelerating and under high engine load

example:

so even if you were cruising down the hwy at 65+ mph and in 4cyl mode and went to pass someone the afm/dod would turn off instantly as soon as you pushed down on the gas pedal you would be running on all 8 cylinders and your boost would come on like normal


and whatever company comes out with a supercharger will probly be including a ecm tuner or you will be sending your ecm to them to be flashed for the supercharger anyways

I dont think it will. I was thinking about that too a while back but I think this is used for engines with turbos so you can keep the boost up.

Good question, somebody here probably has a good answer for that, I know the cylinders continue to move, but I would THINK pushing the gas hard enough to invoke any form of forced induction would bring all the cylinders back online. It only shuts them down under minimal load while doing things like cruising at a steady speed. I don't think that the cylinders would shutdown while you were blipping the throttle or getting ready for a launch at the drag strip, but I will defer to those who know a lot more about such things....
