Using stock ECU for fuel management on this? How man miles on the trans? Anything done to strengthen it up? Ever take it to the track?
Correct the oem PCM has been tuned. I have a wide band in the car, very conservative tune. During wide open throttle , wideband readout is 12.2. The fuel system has been upgraded MSD opti and coil 42LB Bosh green top fuel injectors Walboro 255 fuelpump. The clutch has been upgraded and rated at 700 ft pounds of torque. The t56 is stock and works great. No Grinds. Have not taken to the track, its been more of a highway cruiser. I did plan on road racing however never got to it : ). The car has held together without any issues now for 5 years. Very honest car. Though i will add, if the future owner would like to go for serious hp:
Motor is stout
upgrade to coilpacks
upgrade to a walboro 450 series bigger injectors
strengthen or rebuild the tranny
upgrade the driveshaft
For these reasons i have kept it at 500whp range. Its fast and reliable hasn't left me stranded been driven to NC and back to Dallas no issues. Thanks
