JOhnny I have 283 RWKW from my SS's (-9's) and if that is all you are after, they should be what you get because there is no lag at all and at 4,000 rpm the car takes off and pulls to 6,500 but then seems to not keep pulling harder and harder which is what I want and which is why i need 2530 (-5s) but if you are only seeking the 250 to 270 quoted the (7's or 9's) should do it awesomely:
FYI only

haha the line on the boost that does NOT taper off but stays at 17 psi is my hand writing trying to ask why my boost will not stay on that line! the GTSS kit came with the HKS heavy duty actuators so I cant figure out why it is doing it, must be something to do with the EVC6 settings. Even if I set my boost to 18psi I have not seen more than 17.2 although I have not been hard on anything more than 3rd gear (cos I do not want to lose my license and am waiting to go to the drags next week)
Paul... nice try, but not made of money, if you or Ben from Racepace or anyone else that knows anything about getting 330 SAFE rwkw from a GTSS set up on a stock bottom end 26 comes to WA, ill politely interrupt your holiday for a few hours and fill you up with beer, wine, soft drink and food and take you out for the night
