    Never done any Dodge tuning with HP stuff. Have a customer with a 2012 Ram 1500 5.7 who wants to do a cylinder shut off delete kit.

    Thoughts on speed density only tune?

    I'm primarily a Ford tuner, but I recently bought a WS6 02 Trans Am that has been tuned full time speed density (there's no MAF either). I am curious what people's thoughts are on this method for GM...

    I don't believe it's a dashpot issue, as there wasn't a dashpot issue before changing injector size (on multiple vehicles).

    I'm almost certain, that the issue is I've...

    Hanging idle seems to be a common issue when running FRPP/Deka 80 lb injectors, especially on older EEC5 PCMs. Anyone have suggestions on how to resolve that? Thanks in advance.

    Yeah, looks like B.

    What's got me confused, is that I have a return signal back to the PCM. I've got 1.9 volts on the signal return wire.

    I have that same pic on my Mitchell. Those wires are going to their corresponding letters, however the actual sensor pinout I found has B in the middle.

    Looking at the sensor on the motor, I have it wired Dark blue (5v) at the bottom, BRN (ground) in the middle, and Dark Blue/white (signal return) at the top of the sensor. The truck is a 2010.
