Dear All, My GS300 was stock and Now i fixed a Tanabe medalion Exaust and SRT intake with ECU in it, but with a big "BUT" I didnt feel the 35-25 HP increase. I was hoping to wash a 98 maunal Maxima which has a muffler and Racing Filter only but It Washmed me with a Car Differance. Any Advices on if I fixed it wronge or somthing because i was hoping to feel the imporvement in a much better way than this. Regards
