I had my rex in for a tune check up last week and we found that I need a AOS to solve a blowby problem. After getting this sorted I thought about revisiting the TMIC I have installed. Its nothing special but tis working fine with the car making around 200atw
(2003 WRX, VF34/P20, injectors, pump, 3" TBE, APS CAI, upgraded TMIC.)
I am wondering what sort of benefits I could expect from upgrading to FMIC.
Is there a rough ball park figure to expect in improved performance.
Would it make tuning easier and give me a smoother power/torque curve?
Would a FMIC allow more aggressive tuning?
