Has anyone out there had the Powerstation stage 4 upgrade fitted to their JDM Sti yet? If so can I have some feed back.

 

Sadam is that the 400+ kit you are on about if it is I will be able to give you some feedback in March, my car is booked in for the 3rd of march for fitting when I was down there last month we did an overlay of my cars map now with one that they had already done it comes on boosts about 200 revs further up but midrange top end it just keeps climbing where mine starts to drop.

 

Yep, thats the one - if you could give me some feed back that would be useful - thanks
