I went to test with my friend's GSR satria. I am driving a kelisa with L7 inside. Stock turine.. SAFC-II and open pod filter. at 1st gear.. i can beat my friend's GSR.. but on 2nd and 3rd.. i feel my car no power on higher RPM... could it be cos i dunt have a heat shield? does it make a world of difference? and my intercooler is top mount.. i have not shifted it down yet.. so bonet has no air scope... Is these 2 factors casing me to lose power at higher RPM? at low RPM no problems.
