I see. Well, if anyone is interested in getting more power out their vantage, than metallic substrate cats are a no brainer. I hear there's also a tuner developing headers...between the two, that's probably another 20 hp gain right there. A 4.3 litre putting out 440 hp is a lot more of a respectable specific output than 380, that's for sure. Good job mate!
Maroli - The temps were closely monitored and are not showing any signs of overheating. The catalytic converters are being put under more stress, there is not denying that, however, I will be upgrading to high flow cats relatively soon.
In theory, it should extend the life of the catalytic converter since the car is not running so absurdly rich. Usually extremely rich conditions are what cause cats to fail prematurely, so I guess in theory it could actually extend the life of the cats.
Its impossible to determine exactly how it will effect the long term longevity of the cats. Since I will be replacing them sometime in the next few months I am not too worried about it. Metal core cats are much stronger and longer lasting and should be able to handle whatever you can throw at them.
Hope that helps,

Don't think there is one. Your natural speed limiter is the rev limiter in 6th gear 
.
That's why a Vantage S is capable of doing much faster speeds with only 10hp more. It hits the rev limiter much later because of its 7th gear.

Very nice. Can't wait from the remote option. Any chance of putting down a deposit to use some OBD II equipment and then sending it back after the change?
Any idea of the time frame for OBD II remote setup?
Real anxious to try this tune.

I wouldn't mind increasing redline on mine up from the stock 7300 to stretch out the power band, but I'm not sure it's worth it for me. I'd get more power but I think my risk would go up more. For a stock car, 7600 (300 over stock) is the highest I'd want to go.

This is from Car and Driver...it is all what AM gave as official engine specs except that max power is at 7000 rpm.

I agree Tahoe. Will the car take that redline? Quite possibly, but I would rather change the components within the engine to insure that the engine could handle it. Not worth the risk with just a tune only. My .02, however.

I have proof. The code itself stops at 7200rpm and thats where the power starts to drop off. Zero data after 7200 rpm. +300 helps but I still do not feel like it is enough especially in lower gears.
The motor can easily handle it safely over long term. Spoke to a few performance ford engine builders in town and they gave me lots of interesting specs on what these motors can easily handle.

Interesting stuff...I wonder if the ECU cuts fuel at 7200 rpm because the engine continues to accelerate a bit after the fuel cutoff due to inertia. Maybe they arrived at the 7300 redline based on the estimated maximum speed the engine would hit if the fuel was cutoff at 7200 rpm. Just speculation...Mike would have to answer this.
Data logging definitely showed rpms over 7300 from what I saw. If this is the case and fuel cutoff is at 7200, then that will need to be taken into account when adjusting redline.

The redline is set gear specific. 3rd gear is a couple of hundred rpm higher to get 100mph in third gear at redline.
When it hits redline it doesn't cut fuel to limit rpm- it reduces throttle and backs out spark. For this reason the redline cut is smooth not harsh.

For the ECU mod only is there a definitive power increase being officially marketed by the tuning company?
