Rover Ron 'Max Model'?

Tuning-diesels Synergy 2 shop.

I see in the above link Rover Ron has introduced a Max Model. Does anyone know if this is a modified 2a box? Does it have different curves?

I maybe buying this but it says state the max model in the box on the checkout screen, but I cant just see where? Do I just put Max in the comments box?

taken from the page you linked to......

"......STOP PRESS JAN 12. Please state in the box on the checkout screen if want the 'MAX' model. This one is programmed for maximum possible bhp & assumes your engine's fuel system is in first class 100% working order. If you don't state this, we will send you the standard Synergy 2a+........"

I maybe being stupid here, but what box would I state that in on the checkout page? I've just looked at the checkout page. Maybe it's in the credit card/debit card page instead.

dunno mate, email rover ron or ring him to place your order... very friendly, helpful chap he is.....

looks like i'll have to. Thanks.
