Looking at re-flashing the ECU's on my 2001 360 spider. I have upgraded the TCU to the CS TCU and have the CS exhaust system. After careful research im looking at having Mase engineering re-flash the ECU's. I have upgraded F1 pump also. My understanding is you will need the CS MAF's. I have them ready to go as well as the air filter covers. Any feed back would be great.
