Get a remap not a ga plus box is my advice no noticeable difference Well be aware!bought a ga plus off this lot for boxster 2.7 na after doing the 120 kilometres run in time TWICE as Steve said I may have no done it right!m 50 had more rempas than hot dinners unit made no noticeable difference!rang and spoke to guy called Steve says he has one makes a little difference on his cayman but won’t feel like a massive gain ok so said will send back for refund packaged it up better than when received guess what sent via Royal Mail first class recorded then told warehouse staff told them it’s damaged ! Damaged ?destroyed you mean looking at packing the labels don’t even have a crease in them!yet the module was in pieces!not saying the warehouse staff accidentally damaged it when opening wink wink lol but learn a lesson pay for special delivery with £500 insurance cover because these lot not interested go get a remap is my advise I will be posting my results on all Porsche forums to save others the hassle!got pictures but can’t add them for some reason So I now have opened an investigation as surely the post should be opened by reception not warehouse staff?The Royal Mail tracker shows a mad signature says TL1!so the warehouse staff must deal with the postman?and open all the letters?that box is not crushed on the sides the module looks like a hammer has smashed it to bits so let’s see what the postman says about this because I will not allow this situation to go until I know what really happened
