Well I've never even taken it to half throttle on the 300 tune, plus if you move to central IL all you'll see is flat roads. I drive it like an old man with MPG in mind and enjoy watching everyone around me racing off just to get to the next red light first while I just take my time and roll up as it turns green. I don't get why people are always in such a hurry. It cracks me up to see people behind me getting all sorts of pissed off and then when they're able to they floor it to get around me, just to stop right in front of me at the next light ... rinse and repeat all the way across town then we still both get to the same place at the same time. Maybe I'm just getting old (31)!
I did actually think the airflow was really low on the 300. I switched straight to the 300 from the 210 tow tune and just based on feel and sound when I would thought I should be around 15 pounds (based on driving the 210 for a while) I would look at the monitor and see 5-8 pounds. Couldn't believe the difference in airflow between the two. I guess the 210 tow tune was forcing more air through thinking that I was pulling weight? Either way I'm all but positive I've never been above 20 pounds on the 300. I got the tuner to extend the life of my truck (DPF delete) as well as the increased fuel economy. The added power is nice to have if I need it but I have no reason to be hard on it and just want it to last another 10 years without problems.
