I will be honest with you,
its a centrefugal clutch on the compressor,
that means i can drive the car acclerating carefull right upto 80+mph
driving like that i can get 40+mpg.
But if my right foot gets heavy and the compressor is always in,
it goes down to around 15/20mpg.
The ECU has got a piggyback on it, that was fitted and mapped over in
Toyotas F1 factory in Koln Germany.
As for price if i had to i would slide a little.
I know there are Standard tsports with more mileage going for £6500,
i know mods dont add on price but the compressor was a £3000 converstion,and there is only 1 other done after mine in the UK.
