Message: We have installed 3 so far at the shop all 3
trucks showed better performance and gas mileage
2 of the trucks got away with mid range 89 fuel 1
had some slight pinging and is running 92 93 fuel
What they do is reprogram your timing and fuel
curves making them more aggresive, you can also
use it to retrive trouble codes. Not just a tunner
but also doubles as a diagnostic scanner
They can also compensate for bigger or smaller
tires to keep your speedo right on the money and
a few other things.
In my opinion they are an excellent value for what
they can do
Message: Thanx for the feed back larry.My biggest concern is for performance.I work at a dodge dealership (starting an automotive career) that gives me access to a DRB3 scantool for codes and tire size.Iwas also wondering about raising my rev limiter and speed limiter.
