Holden here in Australia when the made the vy adventra 2003 to 2004.
You can't delete anything out of the system or it shuts down into limp mode.
You can flash the tune for it to run and drive but with very limited changes.
It's a pain in the **** to say the least.
But I'm stuck with having to run a stock stall speed so can't be too big of a cam to start with.
Plus when trying to make good hp.
600 at the crank it makes things very difficult.
Also I can't just boost it as we aren't allowed to do that with the weight of the vehicle it's going into.

 

[QUOTE=stockA4;19710742]Looks like my link didn't work.

just google search 54-424-11 to see the cam card.

the 204/218 117.5 lsa cam is a waste of time in most cases Imo[/QUOTE

That factory LS6 had to meet CA low emissions standards, have a decent idle and it still had an underrated 405 horsepower from 346 cubic inches. So IMO it did its job pretty well for the limitations the engineers had to deal with.

 

[QUOTE=Khodges3;20553906]Maybe I should have been more clear with that statement I wasn't trying to offend anyone, I think I can explain what I mean when I say "the LS6 cam is a waste of time in most cases IMO"

the 02-04 LS6 cam was intend for the LS6 Corvette as an upgrade over the 01 spec cam so with a some higher lift and more exhaust duration the car went faster because it's a very light car with a manual gearbox and a nice 3.91:1 final drive.

If you're intended application for this cam is going to be a vehicle any heavier than a C5 that has an automatic with a stock or very tight converter, gearing less than 3.91:1 and or a taller tire than a Vette, oh and don't forget displacements under 346" they suffer the worst from this swap (4.8/5.3 looking at you) and even a larger engine (6.0+) with static compression less than 10.5:1 is going to lose significant low and midrange power and response over the stock camshaft swapping to the LS6.

346" or larger? Compression more than 10:1? Light car like Corvette light? Looose converter or manual gearbox with a light drive line ( definitely not a truck with a big heavy transfer case and big heavy driveshafts and axles) and final drive at least around 3.73:1 with a 26" tire or better?

If so then go ahead and stab that baby and rev it to the moon with a smooth idle and stock reliability!

Otherwise find something else shiny and bumpy that gives more cranking compression as that would be a better fit.

For example my big heavy 04" suburban hauls *** with a little more compression than stock and some good mild cam timing. ​​​​It's a 5.3L with stock diameter tires and factory 4.10 gearing, stock tourqe converter.

I built the 5.3L in it with 4.8L flat top pistons, stock 706 heads and the sdpc LS6 Power Max Camshaft. It's a 204/222 .551"/.570" 112 + 2. Similar duration as the stock LS6 but on much narrower centerlines, giving not only significantly more cranking compression than a factory LS6 camshaft but also more valve overlap due to the narrower lsa.

It's really just comes down to the required intake valve closure for the intended power range of the setup and in most LS engines in factory fitments and even the majority of swaps out there a 42 degree intake valve closure at 0.050" is just not a good fit for the intended power range when something like that power max is closing the valve at 33 degrees

For what it's worth I'm probably going to try the LS7 cam in my 12:1 compression 6.2L just for fun, See it's only 0.8L less than 7.0L and mines more compression 12 vs 11 so it might work pretty well but it still won't be on the ideal center lines for the given durations used.

This is why camming is fun though because the is no ideal perfect camshaft we all should know that by now but some of them still certainly work better than others for any given application. Imagine if you snuck a late LS1 cam (pn1721) in some guys LS6 Z06 when he wasn't around, he'd get in it and drive it again and be like "damn this thing is super punchy all of a sudden! Where did all the extra power come from!?"

 

I agree with you that every vehicle and its intended use, ie towing,off road,drag racing, etc, can use a various cam/head combinations and also important is the axle gear ratio for your specific application/need. FYI-All C5 Z06 vettes came with a 3.42 axle ratio, which is a good gearing for street or drag strip. My 2003 Z06 runs mid 12's stock and gets 26 MPG on the highway!

 

You're right about The 3.42: 1 Jim loves that ratio they put it in everything, I lost my mind there for a moment. It's the gearbox that's different with more aggressive ratios. I was thinking about an old getrag transaxle for some reason. For what it's worth that spcd powermax cam would blow your mind, you'd have more torque than you know what to do with and a solid gain across the entire rev Range still peaking at the same RPM for a little later and You don't even have to change the springs LOL

 

I noticed you have a 2002 Z28 A4. I have a stock 2002 Trans Am WS6 A4 not even 20k miles on it yet. I may buy a Thorton performance chip you plug into DLC under the dash. The one I might get states a 40 HP gain. Any feedback on these?

 

No no no no

Just leave it alone for now don't do that hp tuner keeps reading the sticky around here
