Sorry, what do u mean by it would be better with a 7500rpm cut out? the factory red zone is 6200rpm, u mean we can push over it?
I can tell you, I can feel a big difference between a full tank and an almost empty tank. After a full tank few days ago, I have no mood to push the car.. I am expecting changing the header will have bigger effect than the CAI
Have you restarted the ECU by disconnecting negative of the battery for 10 minutes..
(I just realised that I need to turn the alarm off in order to disconnect the battery)
My driving habit is driving at below 3k RPM most of the time to save petrol, so that's why I cannot feel it..
After I installed my CAI, my car can drive at 60km/h at 6th gear in a little steep road.. That's my benchmark of measuring, before, I cannot... (Dun laugh at me,I know I got a strange driving style)
I have ordered the NST pulley as well, and will put it on next week... (I dunno what I am doing, still want to gamble on the reliability of my car)
May be my fuel consumption can tell, I save 10% of fuel after putting CAI on...may be another 5% after header, I dun know !!!
If you dont really push your car, shouldnt have got headers or CAI? Dont know about you, but since CAI and headers install, my fuel consumption is around the same, except when i have a heavy foot.
I get cut off around 6.3K, i was flicking redline/rev limiter on track but other than that havnt seen how much more it can go, dont really want to, just to be on the safe side as well.
