Has anyone here put a SCT chip in their 5.4L 2 Valve Trucks? Did it make much difference. I am looking for something to help acceleration and torque converter slip on takeoff and also maybe a little better MPG. How much help do they give?

Any opinions

Which is better, the chip or the tuner? With the chip you can switch programs without plugging anything in via a dial on the dash.

Thanks guys

 

The chips/tuners will not effect the stall speed/slip of the torque converter.
I prefer the Diablosport Predator myself. You can alter many functions are are not limited to what the chip has installed. Also, when updates are available, you can easily download them from Diablosport and install them in your Predator. No sending it back for updates.
