Dodgemech or anyone>>>I have heard people say that the computer on Magnum RT does adjustments at certain hours or miles. What can I expect and when? More power? Better gas milage?

Rumor has it at about 30K you wil see a boost in HP and MPG and again at about 60K, this is insider from engineering. Of course if you ask them on the record they will deny it.

 

How can I adjust my RT to have more power and better gas milage now?

 

Thanks, Dodgemech for answer to my question>>>I will have to wait 3 1/2 years to see what happens at 30,000 miles>>> I may not see what happens at 60,000 miles>>>I may trade before 7 years warrany is up or I could be gone by then>>>I am 68 years old now>>>I only average driving our two cars 7,500 a year each. On interstate trips @ 71 MPH I am getting the 25 MPG and more.

Figure that out and you can have my job.

 

I just passed 3000 miles, stuck some Mobil 1 in the Hemi and I'm definately noticing some power & milage improvements.
Before when I'd punch it from a dead stop the tires would chirp a couple of time and off we went.
Now they light right up and the traction control comes on HARD.
My around town (with AC on) mileage is up to a 16.3 average from the 13s.
Don't know if it's the computer but definately a welcome change.

 

You mean that I have to drive my "slow" RT until 30,000 miles before I get the increase?

Just turned 9,000 miles in 10 months, have 21,000 miles to go yet.

Also switched over to Mobil 1 5W20 synthetic oil, does seem to run easier and freer.

Still love the sound when the hemi gets into the upper power band (over 3,000 rpm).
