TWM/FAST setup

[Rwillia4]

I have a 427W with TWM and FAST EFI. I have not done any tweaking (yet) but wonder what others have done. More specifically will you share?

Thanks

D, go find a FAST system dyno dealer that sells and installer of the system. To get ir setup right you are looking at about 2-3 hours of dyno time. Well worth it when done. Don't let your buds or friends start messing with this system unless they do this for a living and have a certified paper from EFI university. You need a wide range O2 sensor in the system and A/F readings for correct running of the car. Rick Lake Ps. you might try TWM or KCR who built the motor and only fine tuning would be needed. You didn't say what was done on the rest of the car, fuel system, regulator, line size, location of O2 sensors (narrow or wide range) and is the ECU is controlling the coolant fan,fuel pump,and NOS.
