    Default Tuning A v6 cdti Auto

    i have found that if i turn my powerklick red tuning box up from the lowest setting 1 oclock, to say 12 oclock ,that the auto gear box doesnt want to change up when flooring it at say 4500 revs when it normaly changes up it wont, it will hold back for 2 or 3 seconds before changing gear , if i enter a motorway and floor it ,it will pin me back in my seat then its like hitting a wall at 4500 revs and holds back then after 2 or 3 seconds it will go like **** off a shovel , is this because the auto box can only handle so much power ?
    can any one shed any light on this ?
    sorry if this has been asked before

    how are you driveing her ? ....are you putting her in d and flooring her or putting her in manual and flooring her ....if you put her into manual mode (across to the + - ) and then floor her she will sort herself out some times when i boot myn in drive (d) the kick down can sometimes be a little tempramental nowt wrong just strange ...try in manual and see how she goes remember dont use the leaver to change gear in manual mode let the engien and box do the work .she will almost red line every gear before selecting another ...

    i am normally driving in d mode , i have tried manual and it still didnt want to change up even with the leaver. it does red line ok in d or manual but its like the gear box doesnt now it should change up, if i left the box turned up then i feel that i will probably blow the engine up . it is fine when i turn it down but you now what its like you always want more power , on the minimum setting it doesnt seem much different that standard to me ,i am actually running it at 2 oclock not 1 oclock because i got it changing gear better at that possition ,so maybe by turning the box down that much it will be less powerfull than with out it ,i am not sure, dont now how these boxes work

    Think it depends on model but mine (2008 Signum Elite 3.0 CDTi Auto) will NOT change up at Red Line when in Manual - only going down the box automatically when hitting low revs in manual mode. Vehicle manual notes this as "normal".
