thanks for the info Alex, i have only had her for 3 weeks and the miltek was already fitted, if it is just the miltek that is fitted would i be better getting anything ells done before i go for a stage 2+ map? is the stage 2+ map a base map or will it be set up for the way my car runs and the mods that are on here?
sorry for all the questions
will it make it better on fuel or will it drink a bit more?
old subaru sti ppp+ driver with 380 bhp so i am used to drinking the fuel but would be nice to drink a little less
No worries.
You need someone to take a look at the car and see what software(if any)is already on it,and also to find out if the HPFP has been upgraded.
As has already been said,for Stg2+,you need the exhaust,CAI and HPFP,and you will definitely need to budget on a new clutch(assuming that it hasn't been changed by the previous owner).
A Stg2+ map can simply be loaded,and left with generic settings,but is far better to be set up on a dyno,and then logged on the road also.
Any decent tuner would check the car over first,then put it on the RR,and find out what it's doing,before going any further.
If you use all of the extra power,it will return poorer MPG figures,but it's easy to simply use the extra torque,and get an improvement instead.
Mine for instance,can still do 30+mpg on the drag into work,but if it's pushed it will get into the low 20s or less.
