So I got 3 tunes from Sean at Hemi Fever.
1. 93 octane MDS ON, TQ Mgmt OFF
2. 93 octane MDS OFF, TQ Mgmt OFF
3. 93 octane MDS OFF, TQ Mgmt ON
#1 was ok, not too bad. #2 was rough. #3 is better but not as good as when I install the stock PCM in the car. That is butter smooth.
Here is whats...
I have a 2000 5.9l, most of the times when i start the engine, i have to hold in the gas pedal for a little to get it started. If i just turn the key the car will start but then die almost immediately. Once the car warms up then i can start and stop it easily. It seems to be worse...
