ok.... thanks for the feedback. Now before I mentioned who tuned it, I just wanted to let you know that I'm happy how the car now performs but just expected to get to about 230 - 240rwkw (not under 218rwkw!). I have no problems with the tuner as 100's of people from here use them and are happy with them - this is the reason why I went with them. Tuner: HPF in SE suburbs of Melbourne. HPF told me that the injectors are at their maximum and the valve springs are very weak. They did quote me for injectors and valve springs. I just wanted to justify if it's worth spending $800 just for valve springs. Looks like it I'll need injectors as well as they seem to go hand in hand from what I have read. Can anyone tell me that if I do nothing, would the valve springs get weaker and do any further damage? Sorry, dont have a boost graph. Btw, how are my AFR's? ALSO, I did mention to HPF that I wanted a safe tune with "slightly" better bottom performance - which I think I got. Who has a car with just typhoon CAI, injectors and valve springs? How many rwkw are you getting and did you need to strengthen the 4 speed auto? - Just curious... Thanks for you help...
