To Pagey1255 and apollo13, looks like I may have got some crossed wires there so my upmost apologies. Good start that then!
Not a spokesperson but having used the product it does what it says on the tin, and very well.
The tune has been set at reasonable expectations for the engine and longevity of all the other components on whatever stage you want to go to, add to this the ability to update, change and turn off a map from your driveway makes it a fairly good option. Stage 1 @ 241 and 2 @ 260ish is pretty good. I can't comment on the other upgrades as not tried them but from the forums they all sound like it's horses for... and all that.
As we know you can go higher but I crunch the miles so I'm airing on the side of caution, when it doesn't commute it will get the full treatment.
