I haven't got the invoice to hand but I think it was around £600.
If the car has adaptive cruise control fitted then the inter-cooler has to be deigned to fit around it.
Revo didn't offer TCU map.
I ask Revo and they said that their map doesn't support HPFP.
Looking at the APR website they quote 7hp increase between Stage 2 and 2+.
I'm running a 98 RON map day-to-day while switching map using Revo's SPS to the 102 RON feels noticeably quicker.
But running the 102 RON map without 102 RON fuel is a bit risky as I'm using 99 RON V-Power and Millers Petrol Power ECOMAX which offers 2 octane boost as the car was still risk of knocking.
I guess you have already seen this post about TTE500 turbo tuning:-
