Sifu's, I'm driving a Er34 GTT Auto, and i've just installed a HKS F-Con IS at N1, during dyno before they plug in the IS my car was at 138 on wheel and after plugging in the IS my car was ar 209 on wheel. ANd the tuner suspect there was some problem with my car which they need to do a diagnose cause they told me that other GTT that they dynoed was not at the range of hp and they also said that 138hp on wheel is like driving a NA car. So can any sifu let me know wat is the correct hp on wheel on a stock er34 gtt auto??? I really feel alot of difference now with a sudden 71hp gain. But even though with such a gain im still in a mist that what is the cause of the problem.
